The documentation for this should appear here shortly: http://libvirt.org/uri.html(If you only see the holding page, then please come back in up to half an hour).
The attached one-liner adds a xen:/// URI, intended as the normal method to connect to the Xen hypervisor on the local machine. This is just a placeholder until I can get around to rewriting the Xen name parsing code in xen_unified.c. This patch makes local (xen:///) and remote (xen://hostname/) Xen URI-style calls possible and hopefully doesn't prevent logical extensions to the Xen URI syntax from being added in future.
Also, I couldn't get file path URIs to work as they seem to be intended, but I haven't looked very closely yet:
