It's a bit more complicated than that….there's no XML stored in the backend. You'd be better off applying the patch over and compile yourself:) The supported way of how to amend the libvirt XML is via VDSM hooks. You need to intercept the created XML and add whatever is needed, see http://www.ovirt.org/VDSM-Hooks, some of the examples can be used as a base for what you're trying to do...
