Subject: [PATCH] This commit fixes the following issue: During the disk
 migration operation, when the VM is turned on, the message is displayed in
 the list of tasks to be performed: Merging snapshots (UNKNOWN into UNKNOWN)
 of disk UNKNOWN. Now the correct values are displayed instead of UNKNOWN.
