Applied, and pushed the corresponding update to QEMU_TAG in
qemu-xen-unstable.

Does this patch need to be backported to earlier Xen releases ?  It
wasn't clear to me whether there is new Xen code in this area without
which the problem (which the patch solves) does not arise; or whether,
conversely, simply running a new guest is sufficient.

Ian.
