brctl show

 ^^^^^^^^^^^^ 
The bridges id is comprised of the mac address of the parent and the
preamble.

So if peth0 is a physical interface and eth0 is a physical interface
with xen I get a free nic card, just kidding.
What is the function of the peth0?
Say one doesn't want to use pethX at all, is that even possible?
I couldn't get vifs to map correctly when I tried, but that could just
be something still not implemented or a bug.
