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

               --memtune 1000
               --memtune hard_limit=100,soft_limit=60,swap_hard_limit=150,min_guarantee=80

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

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

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

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

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.

           <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

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

       --redirdev BUS[,OPTIONS]
           Add a redirected device.

           type
               The redirection type, currently supported is tcp or spicevmc.

           server
               The TCP server connection details, of the form 'server:port'.

           Examples of invocation:

           --redirdev usb,type=tcp,server=localhost:4000
               Add a USB redirected device provided by the TCP server on 'localhost' port 4000.

           --redirdev usb,type=spicevmc
               Add a USB device redirected via a dedicated Spice channel.

       --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

       --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

       --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.

           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
