New subject: Using VDSM to edit management interface

16 Mar 2018

      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.

Kirin.

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   https://galaxy.ansible.com/hudecof/hosts/

Hi oVirt people, I have setup a new cluster consisting of many
oVirt Nodes with a single dedicated oVirt Engine machine. For the
most part things are working, however despite entering the DNS
search domain during install on the Nodes the management interface
is not aware of my search domain and it has not been added to
/etc/resolv.conf (perhaps that is unnecessary?). I eventually
worked out that the DNS search domain should be included in
/etc/sysconfig/network-scripts/ifcfg-ovirtmgmt However as per the
header/warning, that file is generated by VDSM. I assumed that I
should be able to edit the search domain with vdsClient, but when I
run "vdsClient -m" I don't see any options related to network
config. I found the following page on DNS config:
https://www.ovirt.org/develop/release-management/features/network/
allowExplicitDnsConfiguration/
But it does not seem to offer a way of specifying the DNS search domain
...
(other than perhaps directly editing /etc/resolv.conf - which is
generated/managed by Network Manager). nmcli reports that all of my
interfaces (including ovirtmgmt) are "unmanaged". Indeed when I
attempt to run nmtui there is nothing listed to configure. This
should be really simple! I just want to add my local search domain
so I can use the short name for my NFS server. I'd appreciate any
advice.
Thanks in advance, Kirin.
