VIRT-INSTALL(1)             Virtual Machine Manager            VIRT-INSTALL(1)

NAME
       virt-install - provision new virtual machines

SYNOPSIS
       virt-install [OPTION]...

DESCRIPTION
       virt-install is a command line tool for creating new KVM, Xen, or Linux
       container guests using the "libvirt" hypervisor management library.
       See the EXAMPLES section at the end of this document to quickly get
       started.

       virt-install tool supports graphical installations using (for example)
       VNC or SPICE, as well as text mode installs over serial console. The
       guest can be configured to use one or more virtual disks, network
       interfaces, audio devices, physical USB or PCI devices, among others.

       The installation media can be local ISO or CDROM media, or a distro
       install tree hosted remotely over HTTP, FTP, or in a local directory.
       In the install tree case "virt-install" will fetch the minimal files
       necessary to kick off the installation process, allowing the guest to
       fetch the rest of the OS distribution as needed. PXE booting, and
       importing an existing disk image (thus skipping the install phase) are
       also supported.

       Given suitable command line arguments, "virt-install" is capable of
       running completely unattended, with the guest 'kickstarting' itself
       too. This allows for easy automation of guest installs. This can be
       done manually, or more simply with the --unattended option.

       Many arguments have sub options, specified like opt1=foo,opt2=bar, etc.
       Try --option=? to see a complete list of sub options associated with
       that argument, example: virt-install --disk=?

       Most options are not required. If a suitable --os-variant value is
       specified or detected, all defaults will be filled in and reported in
       the terminal output. If an --os-variant is not specified. minimum
       required options, --memory, guest storage (--disk or --filesystem), and
       an install method choice.

CONNECTING TO LIBVIRT
       --connect URI
           Connect to a non-default hypervisor. If this isn't specified,
           libvirt will try and choose the most suitable default.

           Some valid options here are:

           qemu:///system
               For creating KVM and QEMU guests to be run by the system
               libvirtd instance.  This is the default mode that virt-manager
               uses, and what most KVM users want.

           qemu:///session
               For creating KVM and QEMU guests for libvirtd running as the
               regular user.

           xen:///
               For connecting to Xen.

           lxc:///
               For creating linux containers

GENERAL OPTIONS
       General configuration parameters that apply to all types of guest
       installs.

       -n NAME
       --name NAME
           Name of the new guest virtual machine instance. This must be unique
           amongst all guests known to the hypervisor on the connection,
           including those not currently active. To re-define an existing
           guest, use the virsh(1) tool to shut it down ('virsh shutdown') &
           delete ('virsh undefine') it prior to running "virt-install".

       --memory OPTIONS
           Memory to allocate for the guest, in MiB. This deprecates the
           -r/--ram option.  Sub options are available, like 'memory',
           'currentMemory', 'maxMemory' and 'maxMemory.slots', which all map
           to the identically named XML values.

           Back compat values 'memory' maps to the <currentMemory> element,
           and maxmemory maps to the <memory> element.

           To configure memory modules which can be hotunplugged see --memdev
           description.

           Use --memory=? to see a list of all available sub options. Complete
           details at
           <https://libvirt.org/formatdomain.html#elementsMemoryAllocation>

       --memorybacking OPTIONS
           This option will influence how virtual memory pages are backed by
           host pages.

           Use --memorybacking=? to see a list of all available sub options.
           Complete details at
           <https://libvirt.org/formatdomain.html#elementsMemoryBacking>

       --arch ARCH
           Request a non-native CPU architecture for the guest virtual
           machine.  If omitted, the host CPU architecture will be used in the
           guest.

       --machine MACHINE
           The machine type to emulate. This will typically not need to be
           specified for Xen or KVM, but is useful for choosing machine types
           of more exotic architectures.

       --metadata OPT=VAL,[...]
           Specify metadata values for the guest. Possible options include
           name, uuid, title, and description. This option deprecates
           -u/--uuid and --description.

           Use --metadata=? to see a list of all available sub options.
           Complete details at
           <https://libvirt.org/formatdomain.html#elementsMetadata>

       --events OPT=VAL,[...]
           Specify events values for the guest. Possible options include
           on_poweroff, on_reboot, and on_crash.

           Use --events=? to see a list of all available sub options. Complete
           details at <https://libvirt.org/formatdomain.html#elementsEvents>

       --resource OPT=VAL,[...]
           Specify resource partitioning for the guest.

           Use --resource=? to see a list of all available sub options.
           Complete details at
           <https://libvirt.org/formatdomain.html#resPartition>

       --sysinfo OPT=VAL,[...]
           Configure sysinfo/SMBIOS values exposed to the VM OS.

           Some examples:

           --sysinfo host
               Special type that exposes the host's SMBIOS info into the VM.

           --sysinfo emulate
               Sepcial type where hypervisor will generate SMBIOS info into
               the VM.

           --sysinfo bios.vendor=custom or --sysinfo smbios,bios.vendor=custom
               The default type is smbios and allows users to specify SMBIOS
               info manually.

           Use --sysinfo=? to see a list of all available sub options.

           Complete details at
           <https://libvirt.org/formatdomain.html#elementsSysinfo> and
           <https://libvirt.org/formatdomain.html#elementsOSBIOS> for smbios
           XML element.

       --qemu-commandline ARGS
           Pass options directly to the qemu emulator. Only works for the
           libvirt qemu driver. The option can take a string of arguments, for
           example:

             --qemu-commandline="-display gtk,gl=on"

           Environment variables are specified with 'env', for example:

             --qemu-commandline=env=DISPLAY=:0.1

           Complete details about the libvirt feature:
           <https://libvirt.org/drvqemu.html#qemucommand>

       --vcpus OPTIONS
           Number of virtual cpus to configure for the guest. If 'maxvcpus' is
           specified, the guest will be able to hotplug up to MAX vcpus while
           the guest is running, but will startup with VCPUS.

           CPU topology can additionally be specified with sockets, cores, and
           threads.  If values are omitted, the rest will be autofilled
           preferring sockets over cores over threads.

           'cpuset' sets which physical cpus the guest can use. "CPUSET" is a
           comma separated list of numbers, which can also be specified in
           ranges or cpus to exclude. Example:

               0,2,3,5     : Use processors 0,2,3 and 5
               1-5,^3,8    : Use processors 1,2,4,5 and 8

           If the value 'auto' is passed, virt-install attempts to
           automatically determine an optimal cpu pinning using NUMA data, if
           available.

           Use --vcpus=? to see a list of all available sub options. Complete
           details at
           <https://libvirt.org/formatdomain.html#elementsCPUAllocation>

       --numatune OPTIONS
           Tune NUMA policy for the domain process. Example invocations

               --numatune 1,2,3,4-7
               --numatune 1-3,5,memory.mode=preferred

           Specifies the numa nodes to allocate memory from. This has the same
           syntax as "--vcpus cpuset=" option. mode can be one of
           'interleave', 'preferred', or 'strict' (the default). See 'man 8
           numactl' for information about each mode.

           Use --numatune=? to see a list of all available sub options.

       --blkiotune OPTIONS
           Tune blkio policy for the domain process. Example invocations

               --blkiotune 100
               --blkiotune weight=100,device.path=/dev/sdc,device.weight=200

       --cpu MODEL[,+feature][,-feature][,match=MATCH][,vendor=VENDOR],...
           Configure the CPU model and CPU features exposed to the guest. The
           only required value is MODEL, which is a valid CPU model as known
           to libvirt.

           Libvirt's feature policy values force, require, optional, disable,
           or forbid, or with the shorthand '+feature' and '-feature', which
           equal 'force=feature' and 'disable=feature' respectively.

           If exact CPU model is specified virt-install will automatically
           copy CPU features available on the host to mitigate recent CPU
           speculative execution side channel and Microarchitectural Store
           Buffer Data security vulnerabilities.  This however will have some
           impact on performance and will break migration to hosts without
           security patches. In order to control this behavior there is a
           secure parameter. Possible values are on and off, with on as the
           default. It is highly recommended to leave this enabled and ensure
           all virtualization hosts have fully up to date microcode, kernel &
           virtualization software installed.

           Some examples:

           --cpu core2duo,+x2apic,disable=vmx
               Expose the core2duo CPU model, force enable x2apic, but do not
               expose vmx

           --cpu host
               Expose the host CPUs configuration to the guest. This enables
               the guest to take advantage of many of the host CPUs features
               (better performance), but may cause issues if migrating the
               guest to a host without an identical CPU.

           --cpu host-model-only
               Expose the nearest host CPU model configuration to the guest.
               It is the best CPU which can be used for a guest on any of the
               hosts.

           --cpu
           numa.cell0.memory=1234,numa.cell0.cpus=0-3,numa.cell1.memory=5678,numa.cell1.cpus=4-7
               Example of specifying two NUMA cells. This will generate XML
               like:

                 <cpu>
                   <numa>
                     <cell cpus="0-3" memory="1234"/>
                     <cell cpus="4-7" memory="5678"/>
                   </numa>
                 </cpu>

           --cpu host-passthrough,cache.mode=passthrough
               Example of passing through the host cpu's cache information.

           Use --cpu=? to see a list of all available sub options. Complete
           details at <https://libvirt.org/formatdomain.html#elementsCPU>

       --cputune OPTIONS
           Tune CPU parameters for the guest.

           Configure which of the host's physical CPUs the domain VCPU will be
           pinned to. Example invocation

               --cputune vcpupin0.vcpu=0,vcpupin0.cpuset=0-3,vcpupin1.vcpu=1,vcpupin1.cpuset=4-7

           Use --cputune=? to see a list of all available sub options.

           <https://libvirt.org/formatdomain.html#elementsCPUTuning>

       --security/--seclabel type=TYPE[,label=LABEL][,relabel=yes|no],...
           Configure domain seclabel domain settings. Type can be either
           'static' or 'dynamic'. 'static' configuration requires a security
           LABEL. Specifying LABEL without TYPE implies static configuration.

           Use --security=? to see a list of all available sub options.
           Complete details at
           <https://libvirt.org/formatdomain.html#seclabel>

       --iothreads OPTIONS
           Specify domain <iothreads> and/or <iothreadids> XML. For example,
           to configure <iothreads>4</iothreads>, do:

             --iothreads 4

           Use --iothreads=? to see a list of all available sub options.
           Complete details at
           <https://libvirt.org/formatdomain.html#elementsIOThreadsAllocation>

       --features FEAT=on|off,...
           Set elements in the guests <features> XML on or off. Examples
           include acpi, apic, eoi, privnet, and hyperv features. Some
           examples:

           --features apic.eoi=on
               Enable APIC PV EOI

           --features hyperv.vapic.state=on,hyperv.spinlocks.state=off
               Enable hypver VAPIC, but disable spinlocks

           --features kvm.hidden.state==on
               Allow the KVM hypervisor signature to be hidden from the guest

           --features pvspinlock=on
               Notify the guest that the host supports paravirtual spinlocks
               for example by exposing the pvticketlocks mechanism.

           --features gic.version=2
               This is relevant only for ARM architectures. Possible values
               are "host" or version number.

           --features smm.state=on
               This enables System Management Mode of hypervisor. Some UEFI
               firmwares may require this feature to be present. (QEMU
               supports SMM only with q35 machine type.)

           Use --features=? to see a list of all available sub options.

           <https://libvirt.org/formatdomain.html#elementsFeatures>

       --clock offset=OFFSET,TIMER_OPT=VAL,...
           Configure the guest's <clock> XML. Some supported options:

           --clock offset=OFFSET
               Set the clock offset, ex. 'utc' or 'localtime'

           --clock TIMER_present=no
               Disable a boolean timer. TIMER here might be hpet, kvmclock,
               etc.

           --clock TIMER_tickpolicy=VAL
               Set a timer's tickpolicy value. TIMER here might be rtc, pit,
               etc. VAL might be catchup, delay, etc. Refer to the libvirt
               docs for all values.

           details at <https://libvirt.org/formatdomain.html#elementsTime>

       --pm OPTIONS
           Configure guest power management features. Example:

               --pm suspend_to_memi.enabled=on,suspend_to_disk.enabled=off

           Use --pm=? to see a list of all available sub options. Complete
           details at
           <https://libvirt.org/formatdomain.html#elementsPowerManagement>

       --launch-security TYPE[,OPTS]
           Enable launch security for the guest, e.g. AMD SEV.

           Use --launch-security=? to see a list of all available sub options.
           Complete details at
           <https://libvirt.org/formatdomain.html#launchSecurity>. Example
           invocations:
               # This will use a default policy 0x03
               # No dhCert provided, so no data can be exchanged with the SEV
           firmware
               --launchSecurity sev

               # Explicit policy 0x01 - disables debugging, allows guest key sharing
               --launchSecurity sev,policy=0x01

               # Provide the session blob obtained from the SEV firmware
               # Provide dhCert to open a secure communication channel with SEV firmware
               --launchSecurity sev,session=BASE64SESSIONSTRING,dhCert=BASE64DHCERTSTRING

           SEV has further implications on usage of virtio devices, so refer
           to EXAMPLES section to see a full invocation of virt-install with
           --launchSecurity.

INSTALLATION OPTIONS
       -c, --cdrom PATH
           ISO file or CDROM device to use for VM install media. After
           install, the the virtual CDROM device will remain attached to the
           VM, but with the ISO or host path media ejected.

       -l, --location OPTIONS
           Distribution tree installation source. virt-install can recognize
           certain distribution trees and fetches a bootable kernel/initrd
           pair to launch the install.

           --location allows things like --extra-args for kernel arguments,
           and using --initrd-inject. If you want to use those options with
           CDROM media, you can pass the ISO to --location as well which works
           for some, but not all, CDROM media.

           The "LOCATION" can take one of the following forms:

           https://host/path
               An HTTP server location containing an installable distribution
               image.

           ftp://host/path
               An FTP server location containing an installable distribution
               image.

           ISO Probe the ISO and extract files using 'isoinfo'

           DIRECTORY
               Path to a local directory containing an installable
               distribution image. Note that the directory will not be
               accessible by the guest after initial boot, so the OS installer
               will need another way to access the rest of the install media.

           Some distro specific url samples:

           Fedora/Red Hat Based
               https://download.fedoraproject.org/pub/fedora/linux/releases/29/Server/x86_64/os

           Debian
               https://ftp.us.debian.org/debian/dists/stable/main/installer-amd64/

           Ubuntu
               https://us.archive.ubuntu.com/ubuntu/dists/wily/main/installer-amd64/

           Suse
               https://download.opensuse.org/pub/opensuse/distribution/leap/42.3/repo/oss/

           Additionally, --location can take 'kernel' and 'initrd' sub
           options. These paths relative to the specified location URL/ISO
           that allow selecting specific files for kernel/initrd within the
           install tree. This can be useful if virt-install/ libosinfo doesn't
           know where to find the kernel in the specified --location.

           For example, if you have an ISO that libosinfo doesn't know about
           called my-unknown.iso, with a kernel at 'kernel/fookernel' and
           initrd at 'kernel/fooinitrd', you can make this work with:

             --location my-unknown.iso,kernel=kernel/fookernel,initrd=kernel/fooinitrd

       --pxe
           Install from PXE. This just tells the VM to boot off the network
           for the first boot.

       --import
           Skip the OS installation process, and build a guest around an
           existing disk image. The device used for booting is the first
           device specified via "--disk" or "--filesystem".

       -x, --extra-args KERNELARGS
           Additional kernel command line arguments to pass to the installer
           when performing a guest install from "--location". One common usage
           is specifying an anaconda kickstart file for automated installs,
           such as --extra-args "ks=https://myserver/my.ks"

       --initrd-inject PATH
           Add PATH to the root of the initrd fetched with "--location". This
           can be used to run an automated install without requiring a network
           hosted kickstart file:

           --initrd-inject=/path/to/my.ks --extra-args "ks=file:/my.ks"

       --install
           This is a larger entry point for various types of install
           operations. The command has multiple subarguments, similar to
           --disk and friends. This option is strictly for VM install
           operations, essentially configuring the first boot.

           The simplest usage to ex: install fedora29 is:

             --install fedora29

           And virt-install will fetch a --location URL from libosinfo, and
           populate defaults from there.

           Available suboptions:

           os= This is os install option described above. The explicit way to
               specify that would be --install os=fedora29. os= is the default
               option if none is specified

           kernel=, initrd=
               Specify a kernel and initrd pair to use as install media. They
               are copied into a temporary location before booting the VM, so
               they can be combined with --initrd-inject and your source media
               will not be altered. Media will be uploaded to a remote
               connection if required.

               Example case using local filesystem paths:
                 --install kernel=/path/to/kernel,initrd=/path/to/initrd

               Example using network paths. Kernel/initrd will be downloaded
               locally first, then passed to the VM as local filesystem paths
                 --install
               kernel=https://127.0.0.1/tree/kernel,initrd=https://127.0.0.1/tree/initrd

               Note, these are just for install time booting. If you want to
               set the kernel used for permanent VM booting, use the --boot
               option.

           kernel_args=, kernel_args_overwrite=yes|no
               Specify install time kernel arguments (libvirt <cmdline> XML).
               These can be combine with ex: kernel/initrd options, or
               --location media. By default, kernel_args is just like
               --extra-args, and will _append_ to the arguments that virt-
               install will try to set by default for most --location
               installs. If you want to override the virt-install default,
               additionally specify kernel_args_overwrite=yes

           bootdev=
               Specify the install bootdev (hd, cdrom, floppy, network) to
               boot off of for the install phase. This maps to libvirt
               <os><boot dev=X> XML.

               If you want to install off a cdrom or network, it's probably
               simpler and more backwards compatible to just use --cdrom or
               --pxe, but this options gives fine grained control over the
               install process if needed.

           no_install=yes|no
               Tell virt-install that there isn't actually any install
               happening, and you just want to create the VM. --import is just
               an alias for this, as is specifying --boot without any other
               install options. The deprecated --live option is the same as
               '--cdrom $ISO --install no_install=yes'

       --unattended [OPTIONS]
           Perform an unattended install using libosinfo's install script
           support.  This is essentially a database of auto install scripts
           for various distros: Red Hat kickstarts, Debian installer
           scripting, Windows unattended installs, and potentially others. The
           simplest invocation is to combine it with --install like:

             --install fedora29 --unattended

           A Windows install will look like

             --cdrom /path/to/my/windows.iso --unattended

           Sub options are:

           profile=
               Choose which libosinfo unattended profile to use. Most distros
               have a 'desktop' and a 'jeos' profile. virt-install will
               default to 'desktop' if this is unspecified.

           admin-password-file=
               A file used to set the VM OS admin/root password from. This
               option can be used either as
               "admin-password-file=/path/to/password-file" or as
               "admin-password-file=/dev/fd/n", being n the file descriptor of
               the password-file.  Note that only the first line of the file
               will be considered, including any whitespace characters and
               excluding new-line.

           user-password-file=
               A file used to set the VM user password. This option can be
               used either as "user-password-file=/path/to/password-file" or
               as "user-password-file=/dev/fd/n", being n the file descriptor
               of the password-file. The username is your current host
               username.  Note that only the first line of the file will be
               considered, including any whitespace characters and excluding
               new-line.

           product-key=
               Set a Windows product key

       --boot BOOTOPTS
           Optionally specify the post-install VM boot configuration. This
           option allows specifying a boot device order, permanently booting
           off kernel/initrd with option kernel arguments, and enabling a BIOS
           boot menu (requires libvirt 0.8.3 or later)

           --boot can be specified in addition to other install options (such
           as --location, --cdrom, etc.) or can be specified on its own. In
           the latter case, behavior is similar to the --import install
           option: there is no 'install' phase, the guest is just created and
           launched as specified.

           Some examples:

           --boot cdrom,fd,hd,network
               Set the boot device priority as first cdrom, first floppy,
               first harddisk, network PXE boot.

           --boot kernel=KERNEL,initrd=INITRD,kernel_args="console=/dev/ttyS0"
               Have guest permanently boot off a local kernel/initrd pair,
               with the specified kernel options.

           --boot kernel=KERNEL,initrd=INITRD,dtb=DTB
               Have guest permanently boot off a local kernel/initrd pair with
               an external device tree binary. DTB can be required for some
               non-x86 configurations like ARM or PPC

           --boot loader=BIOSPATH
               Use BIOSPATH as the virtual machine BIOS.

           --boot bootmenu.enable=on,bios.useserial=on
               Enable the bios boot menu, and enable sending bios text output
               over serial console.

           --boot init=INITPATH
               Path to a binary that the container guest will init. If a root
               "--filesystem" has been specified, virt-install will default to
               /sbin/init, otherwise will default to /bin/sh.

           --boot uefi
               Configure the VM to boot from UEFI. In order for virt-install
               to know the correct UEFI parameters, libvirt needs to be
               advertising known UEFI binaries via domcapabilities XML, so
               this will likely only work if using properly configured distro
               packages.

           --boot
           loader=/.../OVMF_CODE.fd,loader.readonly=yes,loader.type=pflash,nvram.template=/.../OVMF_VARS.fd,loader_secure=no
               Specify that the virtual machine use the custom OVMF binary as
               boot firmware, mapped as a virtual flash chip. In addition,
               request that libvirt instantiate the VM-specific UEFI varstore
               from the custom "/.../OVMF_VARS.fd" varstore template. This is
               the recommended UEFI setup, and should be used if --boot uefi
               doesn't know about your UEFI binaries. If your UEFI firmware
               supports Secure boot feature you can enable it via
               loader_secure.

           Use --boot=? to see a list of all available sub options. Complete
           details at <https://libvirt.org/formatdomain.html#elementsOS>

       --idmap OPTIONS
           If the guest configuration declares a UID or GID mapping, the
           'user' namespace will be enabled to apply these.  A suitably
           configured UID/GID mapping is a pre-requisite to make containers
           secure, in the absence of sVirt confinement.

           --idmap can be specified to enable user namespace for LXC
           containers. Example:

               --idmap uid.start=0,uid.target=1000,uid.count=10,gid.start=0,gid.target=1000,gid.count=10

           Use --idmap=? to see a list of all available sub options. Complete
           details at
           <https://libvirt.org/formatdomain.html#elementsOSContainer>

GUEST OS OPTIONS
       --os-variant OS_VARIANT
           Optimize the guest configuration for a specific operating system
           (ex.  'fedora29', 'rhel7', 'win10'). While not required, specifying
           this options is HIGHLY RECOMMENDED, as it can greatly increase
           performance by specifying virtio among other guest tweaks.

           By default, virt-install will attempt to auto detect this value
           from the install media (currently only supported for URL installs).
           Autodetection can be disabled with the special value 'none'.
           Autodetection can be forced with the special value 'auto'.

           Use the command "osinfo-query os" to get the list of the accepted
           OS variants.

STORAGE OPTIONS
       --disk OPTIONS
           Specifies media to use as storage for the guest, with various
           options. The general format of a disk string is

               --disk opt1=val1,opt2=val2,...

           The simplest invocation to create a new 10G disk image and
           associated disk device:

               --disk size=10

           virt-install will generate a path name, and place it in the default
           image location for the hypervisor. To specify media, the command
           can either be:

               --disk /some/storage/path[,opt1=val1]...

           or explicitly specify one of the following arguments:

           path
               A path to some storage media to use, existing or not. Existing
               media can be a file or block device.

               Specifying a non-existent path implies attempting to create the
               new storage, and will require specifying a 'size' value. Even
               for remote hosts, virt-install will try to use libvirt storage
               APIs to automatically create the given path.

               If the hypervisor supports it, path can also be a network URL,
               like https://example.com/some-disk.img . For network paths,
               they hypervisor will directly access the storage, nothing is
               downloaded locally.

           pool
               An existing libvirt storage pool name to create new storage on.
               Requires specifying a 'size' value.

           vol An existing libvirt storage volume to use. This is specified as
               'poolname/volname'.

           Options that apply to storage creation:

           size
               size (in GiB) to use if creating new storage

           sparse
               whether to skip fully allocating newly created storage. Value
               is 'yes' or 'no'. Default is 'yes' (do not fully allocate)
               unless it isn't supported by the underlying storage type.

               The initial time taken to fully-allocate the guest virtual disk
               (sparse=no) will be usually balanced by faster install times
               inside the guest. Thus use of this option is recommended to
               ensure consistently high performance and to avoid I/O errors in
               the guest should the host filesystem fill up.

           format
               Disk image format. For file volumes, this can be 'raw',
               'qcow2', 'vmdk', etc. See format types in
               <https://libvirt.org/storage.html> for possible values. This is
               often mapped to the driver_type value as well.

               If not specified when creating file images, this will default
               to 'qcow2'.

               If creating storage, this will be the format of the new image.
               If using an existing image, this overrides libvirt's format
               auto-detection.

           backing_store
               Path to a disk to use as the backing store for the newly
               created image.

           backing_format
               Disk image format of backing_store

           Some example device configuration suboptions:

           device
               Disk device type. Example values are be 'cdrom', 'disk', 'lun'
               or 'floppy'. The default is 'disk'.

           boot.order
               Guest installation with multiple disks will need this parameter
               to boot correctly after being installed. A boot.order parameter
               will take values 1,2,3,... Devices with lower value has higher
               priority.  This option applies to other bootable device types
               as well.

           target.bus or bus
               Disk bus type. Example values are be 'ide', 'sata', 'scsi',
               'usb', 'virtio' or 'xen'.  The default is hypervisor dependent
               since not all hypervisors support all bus types.

           readonly
               Set drive as readonly (takes 'on' or 'off')

           shareable
               Set drive as shareable (takes 'on' or 'off')

           cache
               The cache mode to be used. The host pagecache provides cache
               memory.  The cache value can be 'none', 'writethrough',
               'directsync', 'unsafe' or 'writeback'.  'writethrough' provides
               read caching. 'writeback' provides read and write caching.
               'directsync' bypasses the host page cache. 'unsafe' may cache
               all content and ignore flush requests from the guest.

           driver.discard
               Whether discard (also known as "trim" or "unmap") requests are
               ignored or passed to the filesystem. The value can be either
               "unmap" (allow the discard request to be passed) or "ignore"
               (ignore the discard request). Since 1.0.6 (QEMU and KVM only)

           driver.name
               Driver name the hypervisor should use when accessing the
               specified storage. Typically does not need to be set by the
               user.

           driver.type
               Driver format/type the hypervisor should use when accessing the
               specified storage. Typically does not need to be set by the
               user.

           driver.io
               Disk IO backend. Can be either "threads" or "native".

           driver.error_policy
               How guest should react if a write error is encountered. Can be
               one of "stop", "ignore", or "enospace"

           serial
               Serial number of the emulated disk device. This is used in
               linux guests to set /dev/disk/by-id symlinks. An example serial
               number might be: WD-WMAP9A966149

           source.startupPolicy
               It defines what to do with the disk if the source file is not
               accessible.  See possible values in
               <https://www.libvirt.org/formatdomain.html#elementsDisks>,
               "startupPolicy" attribute of the <disk> element

           snapshot
               Defines default behavior of the disk during disk snapshots.
               See possible values in
               <https://www.libvirt.org/formatdomain.html#elementsDisks>,
               "snapshot" attribute of the <disk> element.

           See the examples section for some uses. This option deprecates
           -f/--file, -s/--file-size, --nonsparse, and --nodisks.

           Use --disk=? to see a list of all available sub options. Complete
           details at <https://libvirt.org/formatdomain.html#elementsDisks>

       --filesystem
           Specifies a directory on the host to export to the guest. The most
           simple invocation is:

               --filesystem /source/on/host,/target/point/in/guest

           Which will work for recent QEMU and linux guest OS or LXC
           containers. For QEMU, the target point is just a mounting hint in
           sysfs, so will not be automatically mounted.

           Some example suboptions:

           type
               The type or the source directory. Valid values are 'mount' (the
               default) or 'template' for OpenVZ templates.

           accessmode or mode
               The access mode for the source directory from the guest OS.
               Only used with QEMU and type=mount. Valid modes are
               'passthrough' (the default), 'mapped', or 'squash'. See libvirt
               domain XML documentation for more info.

           source
               The directory on the host to share.

           target
               The mount location to use in the guest.

           Use --filesystem=? to see a list of all available sub options.

NETWORKING OPTIONS
       -w OPTIONS
       --network OPTIONS
           Connect the guest to the host network. The value for "NETWORK" can
           take one of 4 formats:

           bridge=BRIDGE
               Connect to a bridge device in the host called "BRIDGE". Use
               this option if the host has static networking config & the
               guest requires full outbound and inbound connectivity  to/from
               the LAN. Also use this if live migration will be used with this
               guest.

           network=NAME
               Connect to a virtual network in the host called "NAME". Virtual
               networks can be listed, created, deleted using the "virsh"
               command line tool. In an unmodified install of "libvirt" there
               is usually a virtual network with a name of "default". Use a
               virtual network if the host has dynamic networking (eg
               NetworkManager), or using wireless. The guest will be NATed to
               the LAN by whichever connection is active.

           type=direct,source=IFACE[,source.mode=MODE]
               Direct connect to host interface IFACE using macvtap.

           user
               Connect to the LAN using SLIRP. Only use this if running a QEMU
               guest as an unprivileged user. This provides a very limited
               form of NAT.

           none
               Tell virt-install not to add any default network interface.

           If this option is omitted a single NIC will be created in the
           guest. If there is a bridge device in the host with a physical
           interface enslaved, that will be used for connectivity. Failing
           that, the virtual network called "default" will be used. This
           option can be specified multiple times to setup more than one NIC.

           Some example suboptions:

           model.type or model
               Network device model as seen by the guest. Value can be any nic
               model supported by the hypervisor, e.g.: 'e1000', 'rtl8139',
               'virtio', ...

           mac.address or mac
               Fixed MAC address for the guest; If this parameter is omitted,
               or the value "RANDOM" is specified a suitable address will be
               randomly generated. For Xen virtual machines it is required
               that the first 3 pairs in the MAC address be the sequence
               '00:16:3e', while for QEMU or KVM virtual machines it must be
               '52:54:00'.

           filterref.filter
               Controlling firewall and network filtering in libvirt. Value
               can be any nwfilter defined by the "virsh" 'nwfilter'
               subcommands. Available filters can be listed by running 'virsh
               nwfilter-list', e.g.: 'clean-traffic', 'no-mac-spoofing', ...

           virtualport.* options
               Configure the device virtual port profile. This is used for
               802.Qbg, 802.Qbh, midonet, and openvswitch config. Check for
               'virtualport' references in the libvirt documentation:
               "https://libvirt.org/formatdomain.html#elementsNICS"

           Use --network=? to see a list of all available sub options.
           Complete details at
           <https://libvirt.org/formatdomain.html#elementsNICS>

           This option deprecates -m/--mac, -b/--bridge, and --nonetworks

GRAPHICS OPTIONS
       If no graphics option is specified, "virt-install" will try to select
       the appropriate graphics if the DISPLAY environment variable is set,
       otherwise '--graphics none' is used.

       --graphics TYPE,opt1=arg1,opt2=arg2,...
           Specifies the graphical display configuration. This does not
           configure any virtual hardware, just how the guest's graphical
           display can be accessed.  Typically the user does not need to
           specify this option, virt-install will try and choose a useful
           default, and launch a suitable connection.

           General format of a graphical string is

               --graphics TYPE,opt1=arg1,opt2=arg2,...

           For example:

               --graphics vnc,password=foobar

           Some supported options are:

           type
               The display type. This is one of:

               vnc

               Setup a virtual console in the guest and export it as a VNC
               server in the host. Unless the "port" parameter is also
               provided, the VNC server will run on the first free port number
               at 5900 or above. The actual VNC display allocated can be
               obtained using the "vncdisplay" command to "virsh" (or
               virt-viewer(1) can be used which handles this detail for the
               use).

               spice

               Export the guest's console using the Spice protocol. Spice
               allows advanced features like audio and USB device streaming,
               as well as improved graphical performance.

               Using spice graphic type will work as if those arguments were
               given:

                   --video qxl --channel spicevmc

               none

               No graphical console will be allocated for the guest. Guests
               will likely need to have a text console configured on the first
               serial port in the guest (this can be done via the --extra-args
               option). The command 'virsh console NAME' can be used to
               connect to the serial device.

           port
               Request a permanent, statically assigned port number for the
               guest console. This is used by 'vnc' and 'spice'

           tlsPort
               Specify the spice tlsport.

           listen
               Address to listen on for VNC/Spice connections. Default is
               typically 127.0.0.1 (localhost only), but some hypervisors
               allow changing this globally (for example, the qemu driver
               default can be changed in /etc/libvirt/qemu.conf).  Use 0.0.0.0
               to allow access from other machines.

               Use 'none' to specify that the display server should not listen
               on any port. The display server can be accessed only locally
               through libvirt unix socket (virt-viewer with --attach for
               instance).

               Use 'socket' to have the VM listen on a libvirt generated unix
               socket path on the host filesystem.

               This is used by 'vnc' and 'spice'

           password
               Request a console password, required at connection time.
               Beware, this info may end up in virt-install log files, so
               don't use an important password. This is used by 'vnc' and
               'spice'

           gl.enable
               Whether to use OpenGL accelerated rendering. Value is 'yes' or
               'no'. This is used by 'spice'.

           gl.rendernode
               DRM render node path to use. This is used when 'gl' is enabled.

           Use --graphics=? to see a list of all available sub options.
           Complete details at
           <https://libvirt.org/formatdomain.html#elementsGraphics>

           This deprecates the following options: --vnc, --vncport,
           --vnclisten, -k/--keymap, --sdl, --nographics

       --noautoconsole
           Don't automatically try to connect to the guest console. The
           default behaviour is to launch virt-viewer(1) to display the
           graphical console, or to run the "virsh" "console" command to
           display the text console. Use of this parameter will disable this
           behaviour.

           Note, virt-install exits quickly when this option is specified. If
           your command requested a multistep install, like --cdrom or
           --location, after the install phase is complete the VM will be
           shutoff, regardless of whether a reboot was requested in the VM. If
           you want the VM to be rebooted, virt-install must remain running.
           You can use '--wait' to keep virt-install alive even if
           --noautoconsole is specified.

VIRTUALIZATION OPTIONS
       Options to override the default virtualization type choices.

       -v
       --hvm
           Request the use of full virtualization, if both para & full
           virtualization are available on the host. This parameter may not be
           available if connecting to a Xen hypervisor on a machine without
           hardware virtualization support. This parameter is implied if
           connecting to a QEMU based hypervisor.

       -p
       --paravirt
           This guest should be a paravirtualized guest. If the host supports
           both para & full virtualization, and neither this parameter nor the
           "--hvm" are specified, this will be assumed.

       --container
           This guest should be a container type guest. This option is only
           required if the hypervisor supports other guest types as well (so
           for example this option is the default behavior for LXC and OpenVZ,
           but is provided for completeness).

       --virt-type
           The hypervisor to install on. Example choices are kvm, qemu, or
           xen.  Available options are listed via 'virsh capabilities' in the
           <domain> tags.

           This deprecates the --accelerate option, which is now the default
           behavior. To install a plain QEMU guest, use '--virt-type qemu'

DEVICE OPTIONS
       All devices have a set of address.* options for configuring the
       particulars of the device's address on its parent controller or bus.
       See "https://libvirt.org/formatdomain.html#elementsAddress" for
       details.

       --controller OPTIONS
           Attach a controller device to the guest. TYPE is one of: ide, fdc,
           scsi, sata, virtio-serial, or usb.

           Controller also supports the special values usb2 and usb3 to
           specify which version of the USB controller should be used (version
           2 or 3).

           Some example suboptions:

           model
               Controller model.  These may vary according to the hypervisor
               and its version.  Most commonly used models are e.g. auto,
               virtio-scsi for the scsi controller, ehci or none for the usb
               controller.  For full list and further details on
               controllers/models, see
               "https://libvirt.org/formatdomain.html#elementsControllers".

           address
               Shorthand for setting a manual PCI address from an lscpi style
               string.  The preferred method for setting this is using the
               address.* parameters.

           index
               A decimal integer describing in which order the bus controller
               is encountered, and to reference the controller bus.

           Use --controller=? to see a list of all available sub options.
           Complete details at
           <https://libvirt.org/formatdomain.html#elementsControllers>

       --input OPTIONS
           Attach an input device to the guest. Example input device types are
           mouse, tablet, or keyboard.

           Use --input=? to see a list of all available sub options. Complete
           details at <https://libvirt.org/formatdomain.html#elementsInput>

       --hostdev OPTIONS
       --host-device OPTIONS
           Attach a physical host device to the guest. Some example values for
           HOSTDEV:

           --hostdev pci_0000_00_1b_0
               A node device name via libvirt, as shown by 'virsh
               nodedev-list'

           --hostdev 001.003
               USB by bus, device (via lsusb).

           --hostdev 0x1234:0x5678
               USB by vendor, product (via lsusb).

           --hostdev 1f.01.02
               PCI device (via lspci).

           --hostdev wlan0,type=net
               Network device (in LXC container).

           --hostdev /dev/net/tun,type=misc
               Character device (in LXC container).

           --hostdev /dev/sdf,type=storage
               Block device (in LXC container).

           Use --hostdev=? to see a list of all available sub options.
           Complete details at
           <https://libvirt.org/formatdomain.html#elementsHostDev>

       --sound MODEL
           Attach a virtual audio device to the guest. MODEL specifies the
           emulated sound card model. Possible values are ich6, ich9, ac97,
           es1370, sb16, pcspk, or default. 'default' will try to pick the
           best model that the specified OS supports.

           This deprecates the old --soundhw option.

           Use --sound=? to see a list of all available sub options. Complete
           details at <https://libvirt.org/formatdomain.html#elementsSound>

       --watchdog MODEL[,action=ACTION]
           Attach a virtual hardware watchdog device to the guest. This
           requires a daemon and device driver in the guest. The watchdog
           fires a signal when the virtual machine appears to hung. ACTION
           specifies what libvirt will do when the watchdog fires. Values are

           reset
               Forcefully reset the guest (the default)

           poweroff
               Forcefully power off the guest

           pause
               Pause the guest

           none
               Do nothing

           shutdown
               Gracefully shutdown the guest (not recommended, since a hung
               guest probably won't respond to a graceful shutdown)

           MODEL is the emulated device model: either i6300esb (the default)
           or ib700.  Some examples:

           Use the recommended settings:

           --watchdog default

           Use the i6300esb with the 'poweroff' action

           --watchdog i6300esb,action=poweroff

           Use --watchdog=? to see a list of all available sub options.
           Complete details at
           <https://libvirt.org/formatdomain.html#elementsWatchdog>

       --parallel OPTIONS
       --serial OPTIONS
           Specifies a serial device to attach to the guest, with various
           options. The general format of a serial string is

               --serial type,opt1=val1,opt2=val2,...

           --serial and --parallel devices share all the same options, unless
           otherwise noted. Some of the types of character device redirection
           are:

           --serial pty
               Pseudo TTY. The allocated pty will be listed in the running
               guests XML description.

           --serial dev,path=HOSTPATH
               Host device. For serial devices, this could be /dev/ttyS0. For
               parallel devices, this could be /dev/parport0.

           --serial file,path=FILENAME
               Write output to FILENAME.

           --serial tcp,host=HOST:PORT,source.mode=MODE,protocol.type=PROTOCOL
               TCP net console. MODE is either 'bind' (wait for connections on
               HOST:PORT) or 'connect' (send output to HOST:PORT), default is
               'bind'. HOST defaults to '127.0.0.1', but PORT is required.
               PROTOCOL can be either 'raw' or 'telnet' (default 'raw'). If
               'telnet', the port acts like a telnet server or client.  Some
               examples:

               Wait for connections on any address, port 4567:

               --serial tcp,host=0.0.0.0:4567

               Connect to localhost, port 1234:

               --serial tcp,host=:1234,source.mode=connect

               Wait for telnet connection on localhost, port 2222. The user
               could then connect interactively to this console via 'telnet
               localhost 2222':

               --serial tcp,host=:2222,source.mode=bind,source.protocol=telnet

           --serial udp,host=CONNECT_HOST:PORT,bind_host=BIND_HOST:BIND_PORT
               UDP net console. HOST:PORT is the destination to send output to
               (default HOST is '127.0.0.1', PORT is required).
               BIND_HOST:BIND_PORT is the optional local address to bind to
               (default BIND_HOST is 127.0.0.1, but is only set if BIND_PORT
               is specified). Some examples:

               Send output to default syslog port (may need to edit
               /etc/rsyslog.conf accordingly):

               --serial udp,host=:514

               Send output to remote host 192.168.10.20, port 4444 (this
               output can be read on the remote host using 'nc -u -l 4444'):

               --serial udp,host=192.168.10.20:4444

           --serial unix,path=UNIXPATH,mode=MODE
               Unix socket, see unix(7). MODE has similar behavior and
               defaults as --serial tcp,mode=MODE

           Use --serial=? or --parallel=? to see a list of all available sub
           options. Complete details at
           <https://libvirt.org/formatdomain.html#elementsCharSerial> and
           <https://libvirt.org/formatdomain.html#elementsCharParallel>

       --channel
           Specifies a communication channel device to connect the guest and
           host machine. This option uses the same options as --serial and
           --parallel for specifying the host/source end of the channel. Extra
           'target' options are used to specify how the guest machine sees the
           channel.

           Some of the types of character device redirection are:

           --channel SOURCE,target.type=guestfwd,target.address=HOST:PORT
               Communication channel using QEMU usermode networking stack. The
               guest can connect to the channel using the specified HOST:PORT
               combination.

           --channel SOURCE,target.type=virtio[,target.name=NAME]
               Communication channel using virtio serial (requires 2.6.34 or
               later host and guest). Each instance of a virtio --channel line
               is exposed in the guest as /dev/vport0p1, /dev/vport0p2, etc.
               NAME is optional metadata, and can be any string, such as
               org.linux-kvm.virtioport1.  If specified, this will be exposed
               in the guest at /sys/class/virtio-ports/vport0p1/NAME

           --channel spicevmc,target.type=virtio[,target.name=NAME]
               Communication channel for QEMU spice agent, using virtio serial
               (requires 2.6.34 or later host and guest). NAME is optional
               metadata, and can be any string, such as the default
               com.redhat.spice.0 that specifies how the guest will see the
               channel.

           Use --channel=? to see a list of all available sub options.
           Complete details at
           <https://libvirt.org/formatdomain.html#elementsCharChannel>

       --console
           Connect a text console between the guest and host. Certain guest
           and hypervisor combinations can automatically set up a getty in the
           guest, so an out of the box text login can be provided
           (target_type=xen for xen paravirt guests, and possibly
           target_type=virtio in the future).

           Example:

           --console pty,target.type=virtio
               Connect a virtio console to the guest, redirected to a PTY on
               the host.  For supported guests, this exposes /dev/hvc0 in the
               guest. See https://fedoraproject.org/wiki/Features/VirtioSerial
               for more info. virtio console requires libvirt 0.8.3 or later.

           Use --console=? to see a list of all available sub options.

           <https://libvirt.org/formatdomain.html#elementsCharConsole>

       --video OPTIONS
           Specify what video device model will be attached to the guest.
           Valid values for VIDEO are hypervisor specific, but some options
           for recent kvm are cirrus, vga, qxl, virtio, or vmvga (vmware).

           Use --video=? to see a list of all available sub options. Complete
           details at <https://libvirt.org/formatdomain.html#elementsVideo>

       --smartcard MODE[,OPTIONS]
           Configure a virtual smartcard device.

           Mode is one of host, host-certificates, or passthrough. Additional
           options are:

           type
               Character device type to connect to on the host. This is only
               applicable for passthrough mode.

           An example invocation:

           --smartcard passthrough,type=spicevmc
               Use the smartcard channel of a SPICE graphics device to pass
               smartcard info to the guest

           <https://libvirt.org/formatdomain.html#elementsRedir>

       --memballoon MODEL
           Attach a virtual memory balloon device to the guest. If the
           memballoon device needs to be explicitly disabled, MODEL='none' is
           used.

           MODEL is the type of memballoon device provided. The value can be
           'virtio', 'xen' or 'none'.  Some examples:

           Use the recommended settings:

           --memballoon virtio

           Do not use memballoon device:

           --memballoon none

           Use --memballoon=? to see a list of all available sub options.

       --tpm TYPE[,OPTIONS]
           Configure a virtual TPM device.

           Type must be passthrough. Additional options are:

           model
               The device model to present to the guest operating system.
               Model must be tpm-tis.

           An example invocation:

           --tpm passthrough,model=tpm-tis
               Make the host's TPM accessible to a single guest.

           --tpm /dev/tpm
               Convenience option for passing through the hosts TPM.

           Use --tpm=? to see a list of all available sub options. Complete
           details at <https://libvirt.org/formatdomain.html#elementsTpm>

       --rng TYPE[,OPTIONS]
           Configure a virtual RNG device.

           Type can be random or egd.

           If the specified type is random then these values must be
           specified:

           backend
               The device to use as a source of entropy.

           Whereas, when the type is egd, these values must be provided:

           backend.source.host
               Specify the host of the Entropy Gathering Daemon to connect to.

           backend.source.service
               Specify the port of the Entropy Gathering Daemon to connect to.

           backend.type
               Specify the type of the connection: tcp or udp.

           backend.source.mode
               Specify the mode of the connection.  It is either 'bind' (wait
               for connections on HOST:PORT) or 'connect' (send output to
               HOST:PORT).

           backend.connect_host
               Specify the remote host to connect to when the specified
               backend_type is udp and backend_mode is bind.

           backend.connect_service
               Specify the remote service to connect to when the specified
               backend_type is udp and backend_mode is bind.

           An example invocation:

           --rng
           egd,backend.source.host=localhost,backend.source.service=8000,backend.type=tcp
               Connect to localhost to the TCP port 8000 to get entropy data.

           --rng /dev/random
               Use the /dev/random device to get entropy data, this form
               implicitly uses the "random" model.

               Use --rng=? to see a list of all available sub options.

               <https://libvirt.org/formatdomain.html#elementsRng>

       --panic MODEL[,OPTS]
           Attach a panic notifier device to the guest. For the recommended
           settings, use:

           --panic default

           Use --panic=? to see a list of all available sub options. Complete
           details at <https://libvirt.org/formatdomain.html#elementsPanic>

       --memdev OPTS
           Add a memory module to a guest which can be hotunplugged. To add a
           memdev you need to configure hotplugmemory and NUMA for a guest.

           Use --memdev=? to see a list of all available sub options. Complete
           details at <https://libvirt.org/formatdomain.html#elementsMemory>.

       --vsock OPTS
           Configure a vsock host/guest interface. A typical configuration
           would be

             --vsock cid.auto=yes

           Use --vsock=? to see a list of all available sub options. Complete
           details at <https://libvirt.org/formatdomain.html#vsock>.

MISCELLANEOUS OPTIONS
       -h
       --help
           Show the help message and exit

       --version
           Show program's version number and exit

       --autostart
           Set the autostart flag for a domain. This causes the domain to be
           started on host boot up.

       --transient
           Use --import or --boot and --transient if you want a transient
           libvirt VM.  These VMs exist only until the domain is shut down or
           the host server is restarted.  Libvirt forgets the XML
           configuration of the VM after either of these events.  Note that
           the VM's disks will not be deleted.  See:
           <https://wiki.libvirt.org/page/VM_lifecycle#Transient_guest_domains_vs_Persistent_guest_domains>

       --destroy-on-exit
           When the VM console window is exited, destroy (force poweroff) the
           VM.  If you combine this with --transient, this makes the virt-
           install command work similar to qemu, where the VM is shutdown when
           the console window is closed by the user.

       --print-xml [STEP]
           Print the generated XML of the guest, instead of defining it. By
           default this WILL do storage creation (can be disabled with
           --dry-run). This option implies --quiet.

           If the VM install has multiple phases, by default this will print
           all generated XML. If you want to print a particular step, use
           --print-xml 2 (for the second phase XML).

       --noreboot
           Prevent the domain from automatically rebooting after the install
           has completed.

       --wait WAIT
           Configure how virt-install will wait for the install to complete.
           Without this option, virt-install will wait for the console to
           close (not necessarily indicating the guest has shutdown), or in
           the case of --noautoconsole, simply kick off the install and exit.

           Bare '--wait' or any negative value will make virt-install wait
           indefinitely.  Any positive number is the number of minutes virt-
           install will wait. If the time limit is exceeded, virt-install
           simply exits, leaving the virtual machine in its current state.

       --dry-run
           Proceed through the guest creation process, but do NOT create
           storage devices, change host device configuration, or actually
           teach libvirt about the guest.  virt-install may still fetch
           install media, since this is required to properly detect the OS to
           install.

       --check
           Enable or disable some validation checks. Some examples are warning
           about using a disk that's already assigned to another VM (--check
           path_in_use=on|off), or warning about potentially running out of
           space during disk allocation (--check disk_size=on|off). Most
           checks are performed by default.

       -q
       --quiet
           Only print fatal error messages.

       -d
       --debug
           Print debugging information to the terminal when running the
           install process.  The debugging information is also stored in
           "~/.cache/virt-manager/virt-install.log" even if this parameter is
           omitted.

EXAMPLES
       The simplest invocation to interactively install a Fedora 29 KVM VM
       with recommended defaults. virt-viewer(1) will be launched to
       graphically interact with the VM install

         # sudo virt-install --install fedora29

       Similar, but use libosinfo's unattended install support, which will
       perform the fedora29 install automatically without user intervention:

         # sudo virt-install --install fedora29 --unattended

       Install a Windows 10 VM, using 40GiB storage in the default location
       and 4096MiB of ram, and ensure we are connecting to the system libvirtd
       instance:

         # virt-install \
             --connect qemu:///system \
             --name my-win10-vm \
             --memory 4096 \
             --disk size=40 \
             --os-variant win10 \
             --cdrom /path/to/my/win10.iso

       Install a CentOS 7 KVM from a URL, with recommended device defaults and
       default required storag,e but specifically request VNC graphics instead
       of the default SPICE, and request 8 virtual CPUs and 8192 MiB of
       memory:

         # virt-install \
              --connect qemu:///system \
              --memory 8192 \
              --vcpus 8 \
              --graphics vnc \
              --os-variant centos7.0 \
              --location http://mirror.centos.org/centos-7/7/os/x86_64/

       Create a VM around an existing debian9 disk image:

         # virt-install \
              --import \
              --memory 512 \
              --disk /home/user/VMs/my-debian9.img \
              --os-variant debian9

       Start serial QEMU ARM VM, which requires specifying a manual kernel.

         # virt-install \
              --name armtest \
              --memory 1024 \
              --arch armv7l --machine vexpress-a9 \
              --disk /home/user/VMs/myarmdisk.img \
              --boot kernel=/tmp/my-arm-kernel,initrd=/tmp/my-arm-initrd,dtb=/tmp/my-arm-dtb,kernel_args="console=ttyAMA0 rw root=/dev/mmcblk0p3" \
              --graphics none

       Start an SEV launch security VM with 4GB RAM, 4GB+256MiB of hard_limit,
       with a couple of virtio devices:

       Note: The IOMMU flag needs to be turned on with driver.iommu for virtio
       devices. Usage of --memtune is currently required because of SEV
       limitations, refer to libvirt docs for a detailed explanation.

         # virt-install \
              --name foo \
              --memory 4096 \
              --boot uefi \
              --machine q35 \
              --memtune hard_limit=4563402 \
              --disk size=15,target.bus=scsi \
              --import \
              --controller type=scsi,model=virtio-scsi,driver.iommu=on \
              --controller type=virtio-serial,driver.iommu=on \
              --network network=default,model=virtio,driver.iommu=on \
              --rng driver,iommu=on \
              --memballoon driver.iommu=on \
              --launchSecurity sev
