Additional info:

from https://bugzilla.redhat.com/show_bug.cgi?id=1325746 :
Engine can be accessed using alternate host names (or IP addresses) that can configured by adding a new configuration file (for example /etc/ovirt-engine/engine.conf.d/99-custom-sso-setup.conf) with following content:

SSO_ALTERNATE_ENGINE_FQDNS="alias1.example.com alias2.example.com"

The list of alternate names has to be listed separated by spaces.

It's possible to add also IP addresses of engine host, but using IP addresses instead of DNS names is not considered to be a good practise.
