How can I roll back to a snapshot?

To restore to the last snapshot, right-click your virtual server and choose Snapshot->Revert to Current Snapshot from the server management interface. If you have more than one snapshot, choose Snapshot->Snapshot Manager.... Then, highlight the desired snapshot and click Go to.

When revert to a snapshot, changes made after the snapshot was taken will be permantly lost. If you would like to retain the changes, make another snapshot before rollback.
