Title:
Network cache should not be refreshed for instances that are still
building
Status in OpenStack Compute (Nova):
Fix Released
Status in OpenStack Compute (nova) havana series:
In Progress
Bug description:
heal_instance_info_cache is a periodic task which refreshes the
network cache for instances on a host. Currently it processes
instances which are still in the building state, which is both
unnecessary (the build itself will update the cache when it completes)
and can lead to a race condition; If the periodic task gets Null
network information (likely as the instance is still being built) but
then gets pre-empted by the build thread and updates the cache after
the instance has finished build has finished then the cache is in
effect cleared.
Simply skipping instances in the building state avoids this situation.
