I've  just upgraded to libvirt 1.2 and live migration using (libvirt to 
copy files rather than shared storage) now taking longer.  This seems to 
be due to it copying the backing files as well as the instances' overlay 
files.  Is there anyway to make it revert to the previous behavior and 
only copy the overlay files?
