PR2 Snapshotting & Restoring

We will use virsh to manage our snapshots of the VMs and their disks.

We'll need some blank file to store our XML data, and then store the XML data from a VM:

touch [backup-name].xml
sudo virsh dumpxml > [backup-name].xml

To make a snapshot:
sudo virsh snapshot-create-as --domain [vm-name] --name [backup-name]

To see the list of snapshots for a certain VM:
sudo virsh snapshot-list --domain [vm-name]

To get remove a snapshot for a VM:
sudo virsh snapshot-delete --domain [vm-name] --snapshotname [vm-snapshot]

To restore your VM from a certain snapshot (make sure to turn it off prior):
sudo virsh snapshot-revert [vm-name] [vm-snapshot]
