If you use shellscript to start qemu then add these flags there. If you are using libvirt - libvirt also supports these features. This mess is looking for a trouble and i believe you found it. libvirt did not add support for this option until 1.3.3. There's nothing wrong with this use of a wrapper script, I would have recommended it in such a situation myself until recently.
