Description Direct Docs Feedback 2023-03-23 18:11:15 UTC 
Maybe we should mention that the first entry of the undercloud name in /etc/hosts for the undercloud IP will be taken and that can cause issues running this playing.

It created in IDM the host `undercloud-162.ctlplane.redhat.local` instead of `undercloud-162.redhat.local` and since the hostname we chose was undercloud-162.redhat.local, it failed on the playbook "add nova service"
