Change subject: engine: Null Pointer Exception when during preview mode action, service ovirt-engine restart ...................................................................... engine: Null Pointer Exception when during preview mode action, service ovirt-engine restart The following bug was caused because of wrong member name, which was caused by not passing serialization by dstSnapshotId, and after restoring it from DB after restart its value was Guid.Empty, so because of that we usually failed at endSuccessfully because of NullPointerException. Thise caused for VM to be stuck in status locked.
