[ovirt-users] Data Center jumping between online and non-responsive

[gregor]

On the host was no dns server set (/etc/resolv.conf). Is it save to edit the network parameter in /etc/sysconfig/network-scripts or is there another way and where can I check if the HostedEngine has the right dns server configured?

cheers
