Public bug reported:

This is on pike with ff747792b8f5aefe1bebb01bdf49dacc01353348 (on
b58c7f033771e3ea228e4b40c796d1bc95a087f5 to be percice).  Live
migrations seem to be stuck at 1MiB/s for linuxbridge VMs.  The code
actually looks like it should fail with a timeout (never see the network
interface created debug message), not sure why it succeeds.
