- As new hosts are added to Nova, the `nova-manage cell_v2
discover_hosts` command must be run in order to map them into
their cell. For deployments with proper automation, this is a
trivial extra step in that process. However, for smaller or
non-automated deployments, there is a new configuration variable
for the scheduler process which will perform this discovery
periodically. By setting
`scheduler.discover_hosts_in_cells_interval` to a positive value,
the scheduler will handle this for you. Note that this process
involves listing all hosts in all cells, and is likely to be too
heavyweight for large deployments to run all the time.
