Time keeping is a common problem of emulators.

Maybe changing kern.timecounter.hardware helps.
Virtualbox also has multiple options.

As a wild guess (I'm not using virtualbox), enabling HPET
in virtualbox and ensuring that the NetBSD timecounter
is also using HPET sounds like a working option.

That says that for screens 1-6 you configured an unknown type,
that is the second argument to 'screen' in /etc/wscons.conf.

The available types are driver specific and "-" means to
use a driver default. The genfb driver knows only the
screen type "default".
