Hi Daniel,
    that sounds like a good plan and would certainly address the openstack case
but I still feel like hving something in qemu is a good idea as that doesn't 
stop
an alternate fix in libvirt and it helps users that aren't using libvirt and 
qemu
together.

Having said that I'm willing to be directed by the qemu community.  If they 
feel that
a libvirt only fix is best then that's where I'll spend my effort.
 
Yours Tony.
