Description of problem:

When a snapshot preview is performed, the final step is to either 'commit' or 'undo'. 

The audit logs show the same for both options;

 Snapshot-Preview snap1 for VM abc was initiated by admin@internal-authz.
 Snapshot-Preview snap1 for VM abc has been completed.
 Restoring VM abc from snapshot started by user admin@internal-authz.
 VM abc restoring from Snapshot has been completed.


A subset of the engine logs is the same;
