Thanks Keir. It is the qemu-dm. Hmm, not my dilemma is whether it'd be a fairly easy thing to incorporate the newer qemu-dm into a 3.1.x branch... I've made some major changes to the shadow page table code for my work and would rather not try and merge them into 3.2.x if I don't have to at this point.
