Hi Lost,

Sorry out of line email.  Had to join to reply.

all gloss right over to DomU.
Yes, it does work out of the box with certain network cards and  by 
starting with eth0 down. 

3C59X cards work fine as does the tg3 cards.  SK98Lin, NS83820 and SKGE 
(DL530G) cards do not.
Second, bring the box up with eth0 down and let xen bring it up.  If 
eth0 is up, then when the physical interface is moved and reassigned a 
new MAC, it somehow keeps its old IP.  In the network-bridge script, an 
arping uses the IP to see if someone owns it and the physical card 
responds.  This causes two ARPs to be broadcast for a given card and  
the message  "eth0: received packet with  own address  as source 
address" to appear in the dmesg and /var/log/messages.
