Title:
Remove unnecessary steps for cold snapshots
Status in OpenStack Compute (Nova):
Fix Released
Status in OpenStack Compute (nova) havana series:
New
Bug description:
When creating cold snapshots we first stop the instance, create a snapshot of
that instance, extract the snapshot to a file, delete the snapshot and bring
the instance back up.
If the instance is stopped, then there's no need to create a snapshot because
there's no concurrent writer, so the snapshot can be extracted directly and
save us from the two unnecessary steps (creation and deletion of a snapshot).
