Its logical to assign vifnames that correspond to the domname + device
as seen within the dom-u.

If my dom-u was named foo, and the device was to become eth0 in foo, I
would name the vif foo.0 , eth1 in foo would be foo.1 , eth2 would be
foo.2 (for a max of three vif's per guest).

This lets me do all of my bandwidth accounting just
reading /proc/net/dev directly with grawk
( http://echoreply.us/2007/04/25/grawk-100-released/ ) rather easily.

I try to avoid snmp or anything else that malloc()s way more than it
needs on dom-0 for obvious reasons :)

Are the guests using the same subnet (netmask) as the the bridge serving
them? In other words, the IP address of your guest not working ends in a
number equal or lesser than the broadcast address of the bridge?
