Title:
live migration of instance should claim resources on target compute
node
Status in OpenStack Compute (nova):
Fix Released
Status in OpenStack Compute (nova) train series:
Fix Released
Bug description:
I'm looking at the current Icehouse code, but this applies to previous
versions as well.
When we create a new instance via _build_instance() or
_build_and_run_instance(), in both cases we call instance_claim() to
test for resources and reserve them.
During a cold migration we call prep_resize() which calls
resize_claim() to reserve resources.
However, when we live-migrate or evacuate an instance we don't do
this. As far as I can see the current code will just spawn the new
instance but the resource usage won't be updated until the audit runs
at some unknown time in the future at which point it will add the new
instance to self.tracked_instances and update the resource usage.
This means that until the audit runs the scheduler has a stale view of
system resources.
