/etc/resolv.conf won't be auto generated.

Ďakujem Peter, but this doesn't seem to work in my case.
/etc/resolv.conf is regenerated by Network Manager after a reboot
and my domain settings are lost. Your comments regarding the
reliance on DNS make sense for most installations, but in my case
oVirt is a secondary service that I would not expect to run unless
our core infrastructure is working correctly. I'm hesitant to edit
/etc/hosts directly, since that can lead to confusion when the
underlying IP addresses change. For now I will hardcode the IPs of
my servers. It's frustrating (and surprising) that there is not an
easy way to do this.

Hi Kirin,
I suggest to do it old way and edit the /etc/resolv.conf manually.
And one advice. Do not relay on the DNS on infrastructure servers.
Use /etc/hosts. If he DNS will not be accessible, you will have
problem to put it infrastructure up/working. As side effect the
hosts allow you to use short names to access servers.
If you are ansible positive, you could use
hudecof.resolv

<
https://galaxy.ansible.com/hudecof/resolv/> hudecof.hosts
