Your suggestion should work, but if something goes wrong libvirt might not
give the best error output, or silently ignore XML configs. To get nice error
reporting you would want to 'virsh define' the XML rather than drop it in
/etc/libvirt, but that's pretty tedious to do for all domains, networks,
autostart, etc.
