qemu sends gratuitous ARP after migration. Check forward delay setting on your bridge interface. It should be set to zero.
Aha! That fixed it. Turns out that debian bridge-utils sets the default to 15 for bridges. Manually setting it to 0 with 'brctl setfd br0 0' or setting the 'bridge_fd' parameter to 0 in /etc/network/interfaces solves the issue.
I think libvirt is doing something about this, copying list for further info. -- I have a truly marvellous patch that fixes the bug which this signature is too narrow to contain.
