Hi Artur,
You are a champion! I can access oVirt now. Thank you so much.
You're welcome!I am happy it worked because I had no more ideas what to
check
next :)
One last question, can I create additional groups in ie. Read Only,
etc? And
then will this be done in KeyCloak or in the oVIrt UI?
This ovirt-administrator group is only for accessing(authentication & sso) ovirt
engine admin panel and, as far as I understand it, it does restrict access
to particular engine's admin functions. I think that proper authorization is
done only at the engine's UI level. See 'User Authorization' under
https://ovirt.org/documentation/admin-guide/chap-Users_and_Roles.html
Thank you

Small clarification:
In keycloak admin panel see Manage-> Groups-> 'ovirt-administrator' ->
Members
Note that the group must have the exact name: ovirt-administrator
