Unfortunately the people who have previously updated the virtualbox driver
for libvirt do not appear to be interested in maintaining it any more.

We thus need someone who is interested in virtualbox to step forward and
volunteer to do work on it in libvirt. Because of the way virtualbox works,
it needs new COM API definitions importing into libvirt for each release,
and sometimes code changes in libvirt to adapt to changesin vbox APIs.

I don't know how much work it would be to update libvirt from vbox 5.2
to newer 6.x versions. It needs someone able todo a little investigation

I would expect that to be working in general.
