echo "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.
