Now i want to bond em1 card with p1p1 card (attached picture net2.jpg) But if i fill the default gw it gives me this error: The default gateway sh= ould be set only on engine network. If i don't fill the default gw, when i click ok, i loose connection to the = server and then after more or less 1 minute the server automaticaly reboots= . Anyone had this kind of problem? Two thoughts here: ;) * The "lose connection to the server" bit sort of sounds like this bug: https://bugzilla.redhat.com/show_bug.cgi?id=3D838816 Reckon that's a match? * Aside from that, you might have to manually configure networking for the hosts from the command line. Using the normal Linux commands I mean, not oVirt specific ones. i.e. creating the bridging and everything manually. This is the approach I had to take last week when trying out Aeolus with oVirt 3.1. Network layer breaks when adding a 2nd interface, but was able to work around it by manually creating the bridges from cli, after having defined the logical networks in the oVirt Web UI. The "configure things manually" approach isn't all that documented either. I kind of stumbled my way through, by looking at the examples here: I second that! I just trial and errored my way through bond -> vlan -> brid= ge. Let=B4s just say that=B4s for people who are up for a challenge.
