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.
Complete details at
<https://libvirt.org/formatdomain.html#elementsNUMATuning>
--memtune OPTIONS
Tune memory policy for the domain process. Example invocations

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

--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.

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

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.
Complete details at
<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

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

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 \
