Re: [ovirt-users] Using VDSM to edit management interface

[Kirin van der Veer]

Hi Peter,
Thanks again for trying to help out on this one.
Unfortunately this sent me right back to where I started.
When you grep for DNS entries the only matching file is
/etc/sysconfig/network-scripts/ifcfg-ovirtmgmt
As per my previous email this file is also generated (by VDSM this time)
and I don't see how to update the VDSM database so that it generates the
file with different entries.
It's turtles all the way down :)

Kirin.

[Peter Hudec]

Remove any settings about dns from the network manager adn the
/etc/resolv.conf won't be auto generated.

Re: [ovirt-users] Using VDSM to edit management interface

[Kirin van der Veer]

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.

Re: [ovirt-users] Using VDSM to edit management interface

[Peter Hudec]

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/

[ovirt-users] Using VDSM to edit management interface

[Kirin van der Veer]

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.
