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
