You might manage to write a vdsm hook to do this, no idea how hard
this can be. See e.g.:

https://www.ovirt.org/develop/developer-guide/vdsm/hooks-catalogue/
https://www.ovirt.org/develop/developer-guide/vdsm/hook/vmdisk/

Latter adds a virtio disk, you might try to write something based on it.

You might try to use a newer kernel. It seems like Fedora 9 or 10 started
supporting virtio, so you can try their kernel.

No idea if it will work, and what might break. Try first on a test VM.
