After setting up one of the network interfaces on the node and confirming I have network I am able to attach it to the engine.  I've done this starting from both the node and the engine and it seems to work either way.  Everything looks good until I go to the network controls in the web interface.  I need to configure another network interface but to do so the ovirtmgmt network must be assigned to an interface.  I'm not sure why it isn't already since the node is already assigned to a cluster.  If I attempt to assign the management network it starts reconfiguring the node and then irrecoverably breaks the network on the node.  By irrecoverable I mean I have to manually log in to the node as root and use ifdown to shut off all of the interfaces, delete all of the network configs under /config and then restart the machine and re-setup the network to get it back.  Nothing less seems to !

>  tore network to the node.  From what I can tell when the node is assigned to a cluster the network looks good on the node side.  It's running a bridge named ovirtmgmt and seems to be happy.  When the engine tries to assign ovirtmgmt to the node it creates a new bridge named after the network interface but is unable to start it.  I've done a lot troubleshooting of network issues on 3.0 and have been able to work around them, but I seem to be at an impasse here.  Without the additional network config my VM's won't work.  Is there another way to force the network configuration without using the web interface?  I know what the network setup should be.  I've done all kinds of manual bridging, bonding, etc. under Fedora.  I just can't seem to get oVirt to understand.

Hi Jacob,

You installed the engine from source? if so what is the engine hash
commit you used for installation?

The reason I am asking that is because we had a major regression last
week were we broke the network API. It was fixed in commit
fa95ed435ac824ae7fc721239d862337053202bc, I suggest you don't cherry
pick this specific commit but rebase on it.

Thanks, Livnat
