In my case they are both empty, but when I installed hosts I configured them This is typically ovirtmgmt network, as in my case, I think. I have also opened a case for another environment where I'm using RHV-H hosts, that should be quite similar to ovirt-node-ng In that environment one of the original M$ based dns server was changed (that was the one I had as primary) creating some latency problems. Using setup host networks generated big problems, especially if doing on the host where hosted engine was running. I verified that a safe way to modify DNS config is: - evacuate VMs from host - put host into maintenance - change dns settings in setup host networks - reboot the host - activate the host This way the "persistent" files are initially updated and then at the reboot the ifcfg and resolv.conf files are correctly updated If you are interested my case is 02179117 Also in that environment the config pages (hosts and logical network of cluster) had empty DNS entries.... I have not understood if the hosts in "setup host network" (and also ovirtmgmt logical network) having empty DNS config is a bug or it's me not understanding the workflow when adding a host to the oVirt environment.
