NAME
virt-image - create virtual machines from an image descriptor
SYNOPSIS
virt-image [OPTION]... IMAGE.XML
DESCRIPTION
virt-image is a command line tool for creating virtual machines from an
XML image descriptor "IMAGE.XML" (virt-image(5)). Most attributes of
the virtual machine are taken from the XML descriptor (e.g., where the
files to back the virtual machine’s disks are and how to map them into
the guest), though certain information must be added on the command
line, such as the name of the guest.
The XML descriptor defines most attributes of the guest, making it
possible to bundle and distribute it together with the files backing
the guest’s disks.
OPTIONS
Most options can be omitted, in which case virt-image will use defaults
from the XML descriptor. When defaults are taken from the XML
descriptor, they are indicated below as a path. --name is the only
required command line option.
-h, --help
Show the help message and exit
--connect=CONNECT
Connect to a non-default hypervisor. See virt-install(1) for
details
General Options
General configuration parameters that apply to all types of guest
installs.
-n NAME, --name=NAME
Name of the guest instance
-r MEMORY, --ram=MEMORY
Memory to allocate for guest instance in megabytes. Defaults to
"/image/devices/memory" in the XML descriptor.
-u UUID, --uuid=UUID
UUID for the guest; if none is given a random UUID will be generated.
If you specify UUID, you should use a 32-digit hexadecimal number.
--vcpus=VCPUS
Number of vcpus to configure for your guest. Defaults to
"/image/devices/vcpu" in the XML descriptor.
--check-cpu
Check that vcpus do not exceed physical CPUs and warn if they do.
--os-type=OS_TYPE
Optimize the guest configuration for a type of operating system (ex.
’linux’, ’windows’). This will attempt to pick the most suitable ACPI
& APIC settings, optimally supported mouse drivers, virtio, and
generally accommodate other operating system quirks. See
virt-install(1) for valid values.
--os-variant=OS_VARIANT
Further optimize the guest configuration for a specific operating
system variant (ex. ’fedora8’, ’winxp’). This parameter is optional,
and does not require an "--os-type" to be specified. See
virt-install(1) for valid values.
Full Virtualization specific options
Parameters specific only to fully virtualized guest installs.
--noapic
Disables APIC for fully virtualized guest (overrides value in XML
descriptor)
--noacpi
Disables ACPI for fully virtualized guest (overrides value in XML
descriptor)
Networking Configuration
-m MAC, --mac=MAC
This is deprecated in favor of "--network ...,mac=MAC,..."
-b BRIDGE, --bridge=BRIDGE
This is deprecated in favor of "--network bridge=BRIDGE"
-w NETWORK, --network=NETWORK
Connect the guest to the host network. See virt-install(1) for
details
Graphics Configuration
If no graphics option is specified, "virt-install" will default to
--vnc if the DISPLAY environment variable is set, otherwise
--nographics is used.
--vnc
Setup a virtual console in the guest and export it as a VNC server in
the host. See virt-install(1) for details
--vncport=VNCPORT
Request a permanent, statically assigned port number for the guest
VNC console. See virt-install(1) for details
--vnclisten=VNCLISTEN
Address to listen on for VNC connections. See virt-install(1) for
details.
-k KEYMAP, --keymap=KEYMAP
Request that the virtual VNC console be configured to run with a non-
English keyboard layout.
--sdl
Setup a virtual console in the guest and display an SDL window in the
host to render the output. See virt-install(1) for details
--nographics
Do not attach a graphical device to the guest. See virt-install(1)
for details
Miscellaneous Options
-p, --print
Print the libvirt XML, but do not start the guest.
--boot=BOOT
The zero-based index of the boot record to use. The XML descriptor
can contain multiple "/image/domain/boot" elements for use on
different hypervisors. By default, the one that is most appropriate
for the current hypervisor is selected.
--replace
Shutdown and remove any existing guest with the passed "--name"
before installing from the image.
--skip-checksum
Do not check disk images against checksums (if they are listed in the
image xml).
-d, --debug
Print debugging information
--force
Prevent interactive prompts. If the intended prompt was a yes/no
prompt, always say yes. For any other prompts, the application will
exit.
EXAMPLES
Create and start a guest called "example" with a VNC console from
"image.xml":
# virt-image --name example --vnc -i image.xml
Print the libvirt XML for a guest called "example" without graphics,
but do not create or start a virtual machine:
# virt-image --print --name example --nographics --image image.xml
