Open Stack

For the list, I'll post the same response i gave you when you pinged me
off-list about this:

t was a long time ago when I wrote that, and the original goal was to use a
single bridge, but there some something about how OVS worked at the time
that required the two bridges.  I think it was related to how the OVS
bridge needed to learn to associate MAC addresses + VLANs to particular
tunnel ports, but I don't remember the details.  This stuff was pretty
simple, so I'm guessing if you mess around with it for a little bit, you'll
either find that it now works (due to some change in OVS) or that it still
doesn't (in which case, it will be obvious why).
