=head1 NAME
virt-image - create virtual machines from an image descriptor
=head1 SYNOPSIS
B<virt-image> [OPTION]... IMAGE.XML
=head1 DESCRIPTION
B<virt-image> is a command line tool for creating virtual machines from an
XML image descriptor C<IMAGE.XML> (L<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.
=head1 OPTIONS
Most options can be omitted, in which case B<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.
=over 4
=item -h, --help
Show the help message and exit
=item --connect=URI
Connect to a non-default hypervisor. See L<virt-install(1)> for details
=back
=head2 General Options
General configuration parameters that apply to all types of guest installs.
=over 2
=item -n NAME, --name=NAME
Name of the guest instance
=item -r MEMORY, --ram=MEMORY
Memory to allocate for guest instance in megabytes. Defaults to
C</image/devices/memory> in the XML descriptor.
=item -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.
=item --vcpus=VCPUS
Number of vcpus to configure for your guest. Defaults to
C</image/devices/vcpu> in the XML descriptor. This option can also be
used to set CPU topology, please see L<virt-install(1)> for more info.
=item --cpuset
Set which physical cpus the guest can use. Please see L<virt-install(1)> for
more info.
=item --cpu
Configure the CPU and CPU features exposed to the guest. Please see
L<virt-install(1)> for more info.
=item --check-cpu
Check that vcpus do not exceed physical CPUs and warn if they do.
=item --os-variant=OS_VARIANT
Optimize the guest configuration for a specific operating system (ex.
'fedora18', 'rhel7', 'winxp'). While not requires, specifying this
options is HIGHLY RECOMMENDED, as it can greatly increase performance
by specifying virtio among other guest tweaks.
See L<virt-install(1)> for valid values.
=back
=head2 Networking Configuration
=over 2
=item -w NETWORK, --network=NETWORK
Connect the guest to the host network. See L<virt-install(1)> for details
=item -m MAC, --mac=MAC
This is deprecated in favor of C<--network ...,mac=MAC,...>
=item -b BRIDGE, --bridge=BRIDGE
This is deprecated in favor of C<--network bridge=BRIDGE>
=back
=head2 Graphics Configuration
If no graphics option is specified, C<virt-image> will default to
'--graphics vnc' if the DISPLAY environment variable is set, otherwise
'--graphics none' is used.
=over 2
=item --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 L<virt-install(1)> for details usage info.
=item --vnc
This option is deprecated in favor of C<--graphics vnc,...>
=item --vncport=VNCPORT
This option is deprecated in favor of C<--graphics vnc,port=PORT,...>
=item --vnclisten=VNCLISTEN
This option is deprecated in favor of C<--graphics vnc,listen=LISTEN,...>
=item -k KEYMAP, --keymap=KEYMAP
This option is deprecated in favor of C<--graphics vnc,keymap=KEYMAP,...>
=item --sdl
This option is deprecated in favor of C<--graphics sdl,...>
=item --nographics
This option is deprecated in favor of C<--graphics none>
=back
=head2 Miscellaneous Options
=over 2
=item --print-xml
Print the libvirt XML, but do not start the guest.
=item --boot=BOOT
The zero-based index of the boot record to use. The XML descriptor can
contain multiple C</image/domain/boot> elements for use on different
hypervisors. By default, the one that is most appropriate for the current
hypervisor is selected.
=item --replace
Shutdown and remove any existing guest with the passed C<--name> before
installing from the image.
=item --noreboot
Prevent the domain automatically booting after importing the image.
=item --skip-checksum
Do not check disk images against checksums (if they are listed in the
image xml).
=item -d, --debug
Print debugging information.
=back
=head1 EXAMPLES
Create and start a guest called C<example> with a VNC console from
C<image.xml>:
# virt-image --name example --vnc image.xml
Print the libvirt XML for a guest called C<example> without graphics, but
do not create or start a virtual machine:
# virt-image --print --name example --nographics image.xml
