Title:
Hyper-V: snapshot fails if the instance is destroyed beforehand
Status in OpenStack Compute (nova):
Fix Released
Bug description:
Instance destroy and Instance snapshot are locking operations, meaning
that they can only occur sequencially. This is the result of the
bugfix for https://bugs.launchpad.net/nova/+bug/1461970 .
The problem is that the destroy instance can occur before snapshoting,
resulting in a VM NotFound exception being raised while snapshoting,
as the VM no longer exists. In the logs it can be observed that the
lock was being held by "do_terminate_instance", which was then aquired
by "instance_synchronized_snapshot".
This causes failures in some tempest tests.
