Snapshots [since 5.0]:
==========

Snapshots allows Virtual Machines disk images to be frozen and changes are applied to a delta disk image.

Snapshots can also include memory contents if the VM is running.

Create : Create a new snapshot based on current snapshot point.

Delete : Roll back current snapshot into parent snapshot and remove delta image(s).  No data is lost.

Restore : Roll back VM to selected snapshot. The VM must be off to perform a restore.

Troubleshooting
===============

If a snapshot is corrupt you can delete the meta data with this command (dangerous):

  virsh snapshot-delete {vm-name} {snapshot-name} --metadata --current

To list VMs:

  virsh list --all

To list snapshots within VM:

  virsh snapshot-list {vm-name}
