With Xen (and other virtualisation technologies) users often end up with a set of bridges, v-switches, hardware switches, and now switches (albeit limited in capabilities) in virtualisation-aware NICs. It would be very useful to develop a control plane over all these devices to allow them to be sensibly configured from a single point. I know there are some people working on bits of this problem but bringing it all together to work on Xen, using open APIs and protocols so that other technologies could be easily integrated, would help a lot. I'll add this to the list on the wiki, but would be happy to hear from others if they have ideas on this topic. Thanks Kieran
