OK, so I reinstalled yesterday using the prepackaged 3.1 beta yum repository. It's
better. It now correctly assigns the ovirtmgmt network to the node when it is attached.
Unfortunately, I still cannot seem to add a second interface or VLAN without breaking the
networking again. I'm wondering if part of it is an issue with the node. If I try to
configure networking through the admin interface on the node it only lets me configure one
interface. Configuring a second interface breaks the first one. I may try manually
editing the config files on the node, but I'm not sure how the engine will see that.

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
