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. + +=over 4 + +=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 ommitted, +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 is 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. + +=back + =head1 ENVIRONMENT The following environment variables can be set to alter the behaviour -- 1.6.6.1
