[ovirt-users] Access via IP instead of FQDN, as well as login issues (cannot authenticate root)

Hello, I am moving away from PVE, as it does not allow the use of virt-manager from my Linux desktop to control it. So after some searching around, I came across oVirt and I installed CentOS. Now I have two problems. 1, I cannot port forward a hostname or an FQDN. So my ability to remotely control it has gone. I wish to be able to access the webui by IP alone. How do I do this? 2. I cannot login. I get unable to verify login on the machine itself (I installed the Mate desktop for testing purposes) otherwise I get an FQDN warning from any other machine. In the logs I get this, [org.ovirt.engine.core.sso.servlets.InteractiveAuthServlet] (default task-23) [] Cannot authenticate user 'root@internal': Unable to log in. Verify your login information or contact the system administrator.
