[ovirt-users] Re: Need to enable STP on ovirt bridges

Seems like the STP options are so common and necessary that it would be a priority over seldom-used bridge_opts. I know what STP is and I'm not even a networking guy - never even heard of half of the bridge_opts that have switches in the UI. Anyway. I wanted to try the openvswitches, so I reinstalled all of my nodes and used "openvswitch (Technology Preview)" as the engine-setup option for the first host. I made a new Cluster for my nodes, added them all to the new cluster, created a new "logical network" for the internal network and attached it to the internal network ports. Now, when I go to create a new VM, I don't even have either the ovirtmgmt switch OR the internal switch as an option. The drop-down is empy as if I don't have any vnic-profiles.
