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

           <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.

           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 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.

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

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

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

           Use the recommended settings:

           --memballoon virtio

           Do not use memballoon device:

           --memballoon none

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

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

           Type must be passthrough. Additional options are:

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

           An example invocation:

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

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

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

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

           Type can be random or egd.

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

           backend
               The device to use as a source of entropy.

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

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

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

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

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

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

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

           An example invocation:

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

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

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

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

           --panic default

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

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

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

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

             --vsock cid.auto=yes

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

MISCELLANEOUS OPTIONS

       -h
       --help
           Show the help message and exit

       --version
           Show program's version number and exit

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

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

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

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

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

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

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

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

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

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

       -q
       --quiet
           Only print fatal error messages.

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

EXAMPLES

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

         # sudo virt-install --install fedora29

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

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

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

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

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

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

       Create a VM around an existing debian9 disk image:

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

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

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

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

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

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