I changed my DNS servers since installing my hosted engine and hosts. I've manually set my /etc/resolv.conf to have the correct nameserver entries. But I found when I rebooted that it was being overwritten. I did some googling and found that in /var/lib/vdsm/persistence/netconf/nets/ovirtmgmt (My management network name) there is a nameservers config that gets applied when vdsm starts which updated my ifcfg files. I edited that file to include my correct name servers.

Now, if I choose a host, go to the network interfaces tab, then click "Setup Host Network" when I exit out with the "Save" checkbox checked, the file in the vdsm directory is being changed back to my old nameserver entry.

I searched all over the hosted engine UI and I can't find where that's old entry is coming from. Where do I go to change this?

Thanks
