I applied this patch to unstable's valgrind, and have now performed a
migration in both directions (see attached).

Can I suggest you try the kernel from jessie-backports? That's what I'm
using; I have kernel 4.2.0 (I needed this because 3.6 from jessie
doesn't support some of my hardware when running Xen).

This is a 1G guest again, and you'll see that receiving version gets
through over 4G.

Matthew
