+The following are additional requirements for xref:../../machine_management/adding-rhel-compute.adoc[Adding RHEL compute machines to an {product-title} cluster],
+when the cluster has been deployed on {rh-openstack-first}:
+
+* The RHEL compute nodes being added and the host that executes the playbooks, need to be able to access the cluster api
+endpoints using dns resolvable hostnames.
+
+* Security groups must be configured such that RHEL compute nodes and the host executing the playbooks are allowed to
+access the cluster api endpoints. This can be tested by trying to access the api tcp port being used by the cluster
+from an user account on the hosts.  The default tcp port for api access to the cluster is 6443.
