It doesn't report that the feature negotiation goes wrong before printing its
features, so the host is accepting v1 but nothing else and that should be OK.

Clumsy error reporting of VirtualBox! What parameter, what call etc.

Could you please test the code with vioscsi revision 0? i.e. with `legacy'
setting? Or/and the setting 'Virtio SCSI Single' if applicable?
Also please boot the kernel with `netbsd -vx'?

Is there a way to get better error message?
