Yes, patches have been proposed to upstream qemu for that feature, but
they missed 1.6, so you will have to wait for qemu 1.7.  There may also
be some integration efforts that require tweaks to libvirt to take
advantage of the qemu feature (the libvirt API was designed to work as
soon as qemu added support, but we haven't yet proven whether our plans
work out as nicely as we hope).
