Title:
  nova [scheduler] tries to schedule an instance on a out of service
  compute host

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  I have an openstack setup (icehouse) with 1 controller + 2 compute
  nodes, where one of the compute nodes was taken out of service. Now
  when running our tests, I observe that a new instances is trying to
  launch on the down compute node.

  How can I debug this further?

  Here are the relevant details:
