Starting in the Ocata release, Nova requires a `Cells v2`_ deployment. Compute
node services must be mapped to a cell before they can be used.
After each compute node is stacked, verify it shows up in the
``nova service-list --binary nova-compute`` output. The compute service is
registered in the cell database asynchronously so this may require polling.
Once the compute node services shows up, run the ``./tools/discover_hosts.sh``
script from the control node to map compute hosts to the single cell.
The compute service running on the primary control node will be
discovered automatically when the control node is stacked so this really
only needs to be performed for subnodes.
