Existing instances can be mapped to a newly created cell immediately after the cell is created and by the same conductor host that created the cell. After a new compute host is built, it will need to mapped to a cell through the 'discover_hosts' command of nova-manage. This command will still need to be run against a host that has direct database access, but the command is able to handle mapping of all compute hosts that do not currently belong to the cell so it only needs to be run once per play. There can be a short delay in the time between a compute service starting and becoming available to be discovered and mapped but, for most deployments, compute host discovery will be handled automatically as a periodic task.
