I just installed a new 3.1 engine and I have one node with the latest node iso 
installed.  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 res
 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.
