Title:
  Increasing number of InstancePCIRequests.get_by_instance_uuid RPC
  calls during compute host auditing

Status in OpenStack Compute (nova):
  Fix Released
Status in nova package in Ubuntu:
  Triaged

Bug description:
  Environment: Ubuntu 14.04/OpenStack Juno Release

  The periodic auditing on compute node becomes very RPC call intensive
  when a large number of instances are running on a cloud; the
  InstancePCIRequests.get_by_instance_uuid call is made on all instances
  running on the hypervisor - when this is multiplied across a large
  number of hypervisors, this impacts back onto the conductor processes
  as they try to service an increasing amount of RPC calls over time.
