I am not so convinced about this one. I think there exist some
applications which want to distinguish between "Xen" and "xenlight". If
a application (like Openstack) doesn't want, nothing is easier than:
type = virConnectGetType(conn);
if (!strcmp(type, "Xen") || !strcmp(type, "xenlight")) {
DoTheMagic();
} else {
ReportError("XEN not supported);
}
IOW I think this is an OpenStack bug, not a libvirt one.
