One of the methods for controlling node placement in OSP 16 is to use scheduler hints. We don't seem to cover this in the director guide but it is documented upstream at https://docs.openstack.org/project-deploy-guide/tripleo-docs/latest/provisioning/node_placement.html. Issue reporter was not able to deploy an overcloud without scheduler hints for node placement.
