Description of problem:
When using localhost.localdomain as FQDN for my engine, I'm getting a warning that not everything will be working which is fine, but then after confirming firewall configuration I get the same warning 3 additional times.

Version-Release number of selected component (if applicable):
ovirt-engine-setup-4.4.0-0.6.master.el7.noarch

How reproducible:
always

Steps to Reproduce:
1. install engine on a server without dns resolution
2. confirm localhost.localdomain or localhost as FQDN for engine (or just set it to such)
3.

Actual results:
warning appears once and then 3 times

Expected results:
warning appears only once

Additional info:

Comment 1 Yedidyah Bar David 2019-12-05 10:45:31 UTC 
The reason that this warning appears 3 more times, is that we use the function that generates it 3 more times - for imageio-proxy, vmconsole-proxy, and websocket-proxy setup plugins. Each of them does its own (duplicate, in this case) tests for the fqdn, which emit this warning. I think it's fine to close, as this is a corner case, harmless, one might even claim desired. Thanks for the report!

Didi, why is this a corner case?

Because people are not supposed to use 'localhost' for the fqdn.
Comment 4 Sandro Bonazzola 2019-12-11 08:10:52 UTC 
Closing wontfix. localhost shouldn't be used for fqdn on engine.
