I could indeed, the issue I saw yesterday is resolved already. I was 
merely thinking we might have a potential single point of failure here.
While the primary nameserver was offline the machine (where the 
ovirt-engine is running) itself had no problem doing name-resolution, 
still oVirt-ui was acting rather unpleasant.
And since my changes to resolv.conf only had an impact after restarting 
the engine I thought there are some internals, such as a cache causing 
this problem.

I can't say for sure if this was due to long delays, but some operations 
in the UI, I was waiting for several minutes before cancelling. And I 
believe that is more than enough time for the OS to try a second 
nameserver.

But this could by all mean have something to do with my 
infrastructure/setup. So let me do some more digging, and if I'm wrong, 
my apologies for the noise.

Brgds,
Jonas
