[ovirt-devel] May snapshot status be `OK' before snapshot creation finishes?

Hi, a failure of previewing a snapshot with memory has been experienced in OST master suite and I'm not sure whether REST API responses about snapshot status are correct or not. When I'm creating a snapshot with memory, <snapshot_status> reported from Engine REST API in /api/vms/…/snapshots is initially `locked' and later switches to `ok'. The problem is that `ok' starts being reported before snapshot creation completes, resulting in errors if I try to stop the VM or to preview the snapshot at the moment. Does <snapshot_status>ok</snapshot_status> guarantee that the snapshot is completed or not? I can see the following example in ovirt-engine-sdk (for snapshot without memory): # 'Waiting for Snapshot creation to finish' snapshot_service = snapshots_service.snapshot_service(snapshot.id) while True: time.sleep(5) snapshot = snapshot_service.get() if snapshot.snapshot_status == types.SnapshotStatus.OK: break So I suppose snapshot status shouldn't switch to OK before snapshot creation finishes. But it's not true in Engine master. Is it a bug or a feature? Thanks, Milan
