i have tried to recreate this bug using both nano cirrius images and
a 4 cpu 1GB Ubuntu image and have not been able to reproduce the behavior sited.

i used the the cirros nano image to test live migrating a very small vm which should have a very short time scale.
in the larger image i ran and iperf server and a iperf client connected over the loopback interface to generate a lot of cup load and memory load to test a longer migrations.

bringing up the br-int interface and sniffing for RARP packets show that the RARP packets are correctly vlan tagged in both cases.

sudo tshark -V -i br-int rarp

unless the original reporter can provide more information on how to reproduce
i will mark this as invalid at the end of the week as it appeares to be fixed.
