Yes (at least with virtio-scsi the libos bits are relatively small; just
think of what it would have been like when the only HBA was LSI), but
with one gotcha...

... sg_utils also parses the pages and dumps them in human-readable
format.  This is useful because it provides a completely separate
implementation and avoids problems with misinterpretation of the
standard.  Of course it would work just as well if someone wrote tests
instead of me.

Ah, understood.  Yeah, a single test is enough for the purpose of
testing QEMU.  If you want to test the driver too, running under Windows
would be useful.
