=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-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 L<virt-install(1)> for valid values.

=item --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 C<--os-type> to be specified. See L<virt-install(1)> for valid
values.

=back



=head2 Full Virtualization specific options

Parameters specific only to fully virtualized guest installs.

=over 2

=item --noapic

Force disable APIC for the guest.

=item --noacpi

Force disable ACPI for the guest.

=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 -p, --print

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
