I hope you had this section queued up for review, and not that you whipped it up in the minute since you responded to that QoS question on ovs-discuss.  I already feel inadequate enough.

I haven't run the commands either, but I think these ports you requested may have been given to br0 and eth0 already, since we try to allocate from 1.  (If you update these ones, there are a couple of places later on that also reference these OpenFlow port numbers.)

Thanks!
