If you are getting an error that there are not enough hosts available, it could be that the cell database was not refreshed. When a compute node is added, the cell database must be refreshed.

Run the following command on your controller:

su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova

you can also set an appropriate interval in /etc/nova/nova.conf on your controller to automatically rediscover compute nodes every so many seconds:

discover_hosts_in_cells_interval = 300

Let me know if that works.
