VNC with a PV guest still works for me, so something else is going on.
The output of `xl -vvv` (domU startup trace) looks fine, beside the
error that say qemu didn't start.

Could you paste also the output of QEMU: at /var/log/xen/qemu-dm-debsid.log
(sorry, logs everywhere)

That patch isn't important. It shouldn't change anything for the
qemu-system-* binaries, but things would changes for others, like
qemu-img, it wouldn't be linked to xen's libs anymore.
