Somewhat related, you may have missed this ML thread: http://lists.openstack.org/pipermail/openstack-discuss/2020-November/019113.html Apparently using an FQDN as your server instance name in the Nova API is considered an antipattern, since the intent is to concatenate it with configured domains for the assigned network. There's even been suggestions to not allow "." in server names at all since some people apparently see that as a security issue (on very specious grounds in my opinion, I definitely don't agree that it's a legitimate risk): https://launchpad.net/bugs/1888722 -- Jeremy Stanley
