Greetings.
We are under the impression if the machine that runs the
    oVirt-engine looses it's primary nameserver, the oVirt web-ui
    becomes more or less unresponsive.
By primary I mean the nameserver at the top of resolv.conf
In 3.x it was a disaster, 4.0 is far better, but for instance
    trying to import storage domains just gives you a spinning wheel
    when it's searching for nfs-domains to display.
By reorder the nameservers in resolv.conf we got it working
    yesterday during our 3.6 ---> 4.0 migration.
Could someone confirm this, please ?
Yes, in order to correctly work, oVirt requires a working DNS also for 
reverse resolution.
Well it's not like the machine (nor oVirt) doesn’t have a working DNS. 
My point is, I'm under the impression it only uses one (the first) from 
resolv.conf and ignores the rest.

Rgds,
Jonas
