We are also using xen 3.0.x, we are not using DHCP, we have static MAC
address in our domU, and we never encountered such a problem in live
migrations.
Maybe another explanation ?
Here is the line that caused trouble to domU.
# vif = [ 'mac=aa:00:00:00:b3:01, bridge=xenbr0' ]
compared to the following that works.
# vif = ['']
It could be due to 'bridge=xenbr0' then.
