discuss at openvswitch.org is another list that you could use. It is
probably a better choice. But we might as well answer your questions as
long as they are here.

That is an imprecise statement. What did you do with brctl, what did
you expect to happen, and what actually happened?

ovs-appctl is the wrong program for this purpose. You should use
"ovs-dpctl show" or "ovs-vsctl list-br" to list bridges.
(Does something in the documentation suggest that you should use
ovs-appctl for this? If it does, then I would like to fix it.)

I'll leave this question for others who are better suited to answer it.
