In the current scenario the controller parsing fails when no index is specified .As the docs point out that specifying index is optional, libvirt is expected to fill the index without erroring out.
See: https://bugzilla.redhat.com/show_bug.cgi?id=1344899 Fixing this is not simple. I've tried to make a simple fix, and it's beyond that (see the BZ and all related email threads that it references for details).

Sure, it doesn't generate an error. But all you've done is make it ignore the fact that the index hasn't been set, you haven't actually set it. NACK.
