Title:
  notification failure in _sync_power_states

Status in OpenStack Compute (Nova):
  Fix Released
Status in OpenStack Compute (nova) havana series:
  New

Bug description:
  The _sync_power_states periodic task pull instances without
  system_metadata in order to reduce network bandwidth being
  unnecessarily consumed.  Most of the time this is fine, but "if
  vm_power_state != db_power_state" then the instance is updated and
  saved.  As part of saving the instance a notification is sent.  In
  order to send the notification it extracts flavor information from the
  system_metadata on the instance.  But system_metadata isn't loaded,
  and won't be lazy loaded.  So an exception is raised and the
  notification isn't sent.
