Title:
  Sporadic 'Failed to get metadata for ip:'

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  I see this error in the nova-api.log (the one from the compute node) when running a stress test that starts/kills vms rapidly. This is from a diablo-stable cluster with one controller and two compute nodes, using multi-host with nova-network and nova-api running on each compute node. It happens maybe 20% of the runs. Is is possible there is a race condition involving tearing down a vm and removing its fixed ip from this database?
  I am working on getting the stress tests checked into Tempest as soon as possible.
