[ovirt-users] Host DNS

[Edward Haas]

We have a gap regarding DNS settings and work is under way to allow DNS to
be set from the manager (Engine).

You seem to got into a loop here, due to the way oVirt agent (VDSM) handles
DNS and its configuration.
Please follow these steps and let us know if it helps:
- Update the entries in  /var/lib/vdsm/persistence/netconf/nets/ovirtmgmt
as you have already done.
- Update the entries in ifcfg-ovirtmgmt.
- Reboot the host.

* Instead of rebooting you could update the temporary running entries
under: /var/run/vdsm/netconf for the ovirtmgmt network.

Thanks,
Edy.
