mhm in which case? Right now i can't imagine a scenario where you want 
to use different drivers. If your guest is not recent enough you'll 
choose scsi-hd. If your guest IS recent enough you'll choose 
scsi-generic as it bypasses the emulation which results in lower CPU 
usage AND in more speed AND more features (discard).

In which situation do you need a mixture of both or all three (i don't 
see any benefits for scsi-block at all)?

Greets,
Stefan
