Sorry, I hate to be "that guy", but does no one here seem to care that both the
repositories and documentation are wrong for installing oVirt on RHEL 7.5? Either the
documentation is wrong, or the RHEL repos require updating.
One or the other is true, and I don't know enough about the oVirt support structure to
know where to submit the appropriate bug report. I'm happy to do so, but I need input
from the community here.
I went ahead and installed the Satellite repo, but there is also an install problem with
the gluster-server package - it never installs. I had to manually install it and manually
launch the daemon and enable it (glusterd).
To see this yourself:
1) Have an existing functional oVirt environment
2) Install RHEL 7.5 onto a new host from an ISO and subscribe it to Red Hat's repos
3) Configure the rhel-7-server-rpms, rhel-7-server-optional-rpms and
rhel-7-server-extras-rpms repos
4) Try to add the new host to the oVirt cluster
5) See the failure
6) Configure the rhel-7-server-satellite-tools-6.3-rpms repo on the RHEL host
7) Try to add the host again
8) See it fail again
9) Install the gluster-server package onto the RHEL 7.5 host
10) Enable the glusterd service and start it
11) Try YET AGAIN to add the RHEL 7.5 host to the cluster
12) Success
So I say again - either the documentation is wrong, or Red Hat's repos require an
update (specifically the Extras repo).
