Public bug reported: 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.
