Title:
  No host-to-cell mapping found for selected host

Status in OpenStack Compute (nova):
  Invalid
Status in tripleo:
  Fix Released

Bug description:
  This report is maybe not a bug but I found useful to share what happens in TripleO since this commit:
  https://review.openstack.org/#/c/319379/

  We are unable to deploy the overcloud nodes anymore (in other words,
  create servers with Nova / Ironic).

  Nova Conductor sends this message:
  "No host-to-cell mapping found for selected host"
  http://logs.openstack.org/31/426231/1/check-tripleo/gate-tripleo-ci-centos-7-ovb-ha/915aeba/logs/undercloud/var/log/nova/nova-conductor.txt.gz#_2017-01-27_19_21_56_348

  And it sounds like the compute host is not registered:

  Nova Config is available here:

  That's all the details I have now, feel free for more details if
  needed.
