Title:
  kilo controller can't conduct juno compute nodes

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  When I tried to use kilo controller to conduct juno compute nodes,
  the juno nova-compute service start with the following two errors:

  Andbody  know is there  something like gate keeper to make kilo controller can keep conducting the juno compute nodes ? Thanks!
