I did some digging around in the kernel logs for the guest post-migration and found an entry that indicates the failure.

Feb  1 18:21:03 XX kernel: netfront: device eth0 has copying receive path.
Feb  1 18:21:03 XX kernel: netfront: device eth1 has copying receive path.
Feb  1 18:21:03 XX kernel: vif vif-3: 2 reading other end details from device/vif/3
Feb  1 18:21:03 XX kernel: xenbus: resume (talk_to_otherend) vif-3 failed: -2
Feb  1 18:21:03 XX kernel: Initializing CPU#1
Feb  1 18:21:03 XX kernel: Initializing CPU#2
Feb  1 18:21:03 XX kernel: Initializing CPU#3

Notice line 3&4.

I'll continue to try and replicate, but if this rings any bells, please comment.
