[ovirt-users] Node network setup

[Edward Haas]

It is not clear to me what you are attempting to do exactly, but networking
settings should be handled through the setup networks window on Engine.
(Network->Hosts->->[specific host]->Interface tab -> SetupNetwork

You can then define bonds by dragging the nics one over the other.

Thanks,
Edy.
