Googling the pertinent text from the above long error:
duplicate key value violates unique constraint "name_server_pkey"
led me to this bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=1530944
and the discovery I had a duplicate DNS IP address in /etc/resolv.conf
Removing this and adding the host again worked :-)
But it shouldn't have been this hard to install oVirt. May I suggest tolarance of
duplicate DNS IPs be added?
In above bug report, Yaniv Kaul says won't fix because it's user error. Perhaps,
but the oVirt installer should do a modicum of hand-holding IMO.
Perhaps. I am not saying this does not make sense. It's a question of
trade-off - between the time spent preparing a patch, testing it,
potentially having to maintain it in the future, etc., and the time
spent debugging such cases when they do happen, and the other damage
caused (not much, in code related only to new setups - it has very low
chances to e.g. corrupt data etc.).
While in many cases we do try to hand-hold, admittedly especially in
cases of more potential for damage, there is a limit to how much we
can do. Or, in other words (also being a sysadmin for 15 years in the
past, and also seeing many support cases in oVirt/RHV), there is
practically _no_ limit to how much a user can do weird things to the
system...
That said, you know the "standard" answer in such cases... (Verified -
that's the hard part - ) Patches are welcome! :-)
Best regards,
