Hello, did you checked under the network configuration of ovirtmgmt on each host? Here there are directives for setting ip, dns and gateway. Since you're reporting a file from vdsm, that configuration can be changed through the manager ui. Luca On Thu, Jan 31, 2019 at 3:25 PM Chris Adams <cma@cmadams.net> wrote:

I am trying to change the DNS servers on the hosts on a 4.1 cluster. It appears that oVirt has "learned" them somewhere. They are in /etc/sysconfig/network-scripts/ifcfg-ovirtmgmt (and of course /etc/resolv.conf), but that file gets rewritten on a reboot (so if I change it they just change back). I can't find anything in the web UI to set/change DNS, but obviously they're stored somewhere.

I see /var/lib/vdsm/persistence/netconf.<number>/nets/ovirtmgmt has the config; is it safe to directly edit that file?
