virt−image − create virtual machines from an image descriptor
virt-image [ OPTION ]... IMAGE .XML
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.
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. This option can also be used to set CPU topology, please see virt−install(1) for more info.
−−cpuset
Set which physical cpus the guest can use. Please see virt−install(1) for more info.
−−cpu
Configure the CPU and CPU features exposed to the guest. Please see virt−install(1) for more info.
−−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
Force disable APIC for the guest.
−−noacpi
Force disable ACPI for the guest.
Networking
Configuration
−w NETWORK ,
−−network=NETWORK
Connect the guest to the host network. See virt−install(1) for details
−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"
Graphics
Configuration
If no graphics option is specified,
"virt−image" will default to
’−−graphics vnc’ 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. See virt−install(1) for details usage info.
−−vnc
This option is deprecated in favor of "−−graphics vnc,..."
−−vncport=VNCPORT
This option is deprecated in favor of "−−graphics vnc,port=PORT,..."
−−vnclisten=VNCLISTEN
This option is deprecated in favor of "−−graphics vnc,listen=LISTEN,..."
−k KEYMAP , −−keymap=KEYMAP
This option is deprecated in favor of "−−graphics vnc,keymap=KEYMAP,..."
−−sdl
This option is deprecated in favor of "−−graphics sdl,..."
−−nographics
This option is deprecated in favor of "−−graphics none"
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.
−−noreboot
Prevent the domain automatatically booting after importing the image.
−−skip−checksum
Do not check disk images against checksums (if they are listed in the image xml).
−d, −−debug
Print debugging information.
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
