[ovirt-users] Re: Newbie question on network

The usual process to add another network bridge is to configure a new cluster logical network in the engine, then configure specific network interfaces on all hypervisors through the engine's "configure host networks".

Another network question: I have a second network card on the host that is connected to an internal switch, how do I add a bridge for that card to be used by the VMs ? I created a secondary bridge on the host and then I tried to play with the network options on the oVirt portal, but I couldn't figure out to associate the new bridge with an new network. Before anyone thinks that the two issues are related, I did this after failing to solve the first issue.
