1. Please don't write to ME personally, unless I initiated such communication 
(I'm not charging for my advice [I'm paid by AMD to develop the Xen kernel, and 
as part of that, I monitor the mailing lists and reply when I think I can offer 
advice.], so it's not fair that some people get advice that others don't have 
access to). Also, I may be an expert on some areas of Xen, but I don't know 
everything. Even if I give an answer, someone else may have a BETTER or 
different answer, and if I'm wrong, someone will most likely say so. If you 
communicate with only me, you would not get those answers.

2. I did see your question, but I didn't think I had a good answer to your 
question - others have (much) more experience with bridge-setups than I do.

3. Bridge-code in Xen is generic bridge code for Linux, so it's not unique (or 
in other ways special) to Xen - not even modified. 

4. What version of Xen are you running and are you running full-virtualization 
(HVM) or para-virtualization (PV) guests?
