  In nova.compute.manager._do_build_and_run_instance we're hitting an
  UnexpectedDeletingTaskStateError exception:

  http://logs.openstack.org/53/169753/2/check/check-tempest-dsvm-full-
  ceph/07dcae0/logs/screen-n-cpu.txt.gz#_2015-04-01_14_34_36_898

  Then we start tearing down here:

  http://logs.openstack.org/53/169753/2/check/check-tempest-dsvm-full-
  ceph/07dcae0/logs/screen-n-cpu.txt.gz#_2015-04-01_14_34_36_905

  And for some reason there are no fixed_ips with no address once we try
  to deallocate in the network manager.
