FWIF, on what is to be VBox 7 I have netbsd vm (currentish kernel)
with root on vioscsi.  generic HBA error is our scsipi trying to use
SCSI_MAINTENANCE_IN and SCSI_MODE_SENSE_6.

Does the same problem exist with other network card type?  "Bridged to
wifi" is a bit fragile and doesn't work correctly with some routers
that try to optimize for performance and ignore broadcast flag in the
DHCP request.
