Looks like this is more or less identical to Peter's proposal to add a
<title> element:
https://www.redhat.com/archives/libvir-list/2012-January/msg00710.html

so I'm all for the idea (not sure whether your patch or Peter's is
better for the idea).

As far as I know, the title is _not_ coming from the hypervisor itself,
nor is it guest-visible; it is merely metadata from the host's perspective.
