=head1 SNAPSHOT COMMMANDS
The following commands manipulate domain snapshots. Snapshots take the
disk, memory, and device state of a domain at a point-of-time, and save it
for future use. They have many uses, from saving a "clean" copy of an OS
image to saving a domain's state before a potentially destructive operation.
Snapshots are identified with a unique name. See
L<http://libvirt.org/formatsnapshot.html> for documentation of the XML format
used to represent properties of snapshots.

=item B<snapshot-create> I<domain> I<xmlfile>
Create a snapshot for domain I<domain> with the properties specified in
I<xmlfile>. The only properties settable for a domain snapshot are the
<name> and <description>; the rest of the fields are ignored, and
automatically filled in by libvirt. If I<xmlfile> is completely omitted,
then libvirt will choose a value for all fields.
=item B<snapshot-current> I<domain>
Output the snapshot XML for the domain's current snapshot (if any).
=item B<snapshot-list> I<domain>
List all of the available snapshots for the given domain.
=item B<snapshot-dumpxml> I<domain> I<snapshot>
Output the snapshot XML for the domain's snapshot named I<snapshot>.
=item B<revert-to-snapshot> I<domain> I<snapshot>
Revert the given domain to the snapshot specified by I<snapshot>. Be aware
that this is a destructive action; any changes in the domain since the
snapshot was taken will be lost. Also note that the state of the domain after
revert-to-snapshot is complete will be the state of the domain at the time
the original snapshot was taken.
=item B<snapshot-delete> I<domain> I<snapshot> I<--children>
Delete the snapshot for the domain named I<snapshot>. If this snapshot
has child snapshots, changes from this snapshot will be merged into the
children. If I<--children> is passed, then delete this snapshot and any
children of this snapshot.
