Hi Antoni:
Yes, prior to the reboot it did work okay. This is how it should look I believe:
Bridge "ovirtmgmt"
Port "mgmt0"
Interface "mgmt0"
type: internal
Port "ovsbr0"
Interface "ovsbr0"
type: internal
So the bridge would be defined by oVirt then I guess with a custom hook that would then be
added to the OVS stack ?
Thanks, Phil

That is what I tried but oVirt appears to overwrite the bridge information on
boot :( Thanks, Phil
But before rebooting, does it work as you intended? If so, you could just make
a vdsm hook that adds ovirtmgmt to the ovs bridge after it is set up. (I could
give more directions into how to do it).

I haven't tried this, and it may not work, but what happens if you add the
ovirtmgmt
bridge as a port of the ovs bridge?
