Not necessarily there is also a priviledged interface via the console for historical reasons For the legacy VGA ports the proper approach is almost certainly to scan the PCI bus routing data and work out which device they are routed to and then attach them to that physical device. That may be a dynamic configuration but you'll see the virtualisation of the PCI config changes any guest tries to do if so.
