I have the same issue with the same configuration(Xen 4.1 + Ubuntu 11.10 
+drbd+lvm), except i use ubuntu 10.10 domu. The issue little differ with yours. 
I can migrate  domu from node to node2 without this network problem, but when i 
migrate this domu from node2 to node1 i get the issue. So i get issue only when 
i migrate domu from node2 to node1.
I tried: 'xm network-detach' and 'xm network-attach' and the network bring 
back. When i repeat migrate to node2, and then migrate to node1 back, the domu 
hang up, and recreating domu on node1 fail because of error: device 0 (vif) 
could not be connected. Hotplug scripts not working.
Only node reboot help.
Nodes have some hardware and software differs. I dont think that hardware 
difference mean. Xen and drbd settings equal. Software difference is: node1 
have 3.0.0-12-generic-pae kernel, and node2 the last 3.0.0-14-generic-pae. 
Maybe this is the reason. I'll to upgrade node1, and if it help i wrote here.
