So why was "SCSI storage controller" any better than "IDE interface" or

Because both ATA and SATA classes have a generic driver that would try
to bind to that controller (and the whole point of virtio block device
is to avoid emulating a ATA/SATA controller).
Doesn't "80 Mass storage controller" ("0x80 0x00 Other mass
storage
controller") fit better for virtio block device?
Maybe. I guess that are compatibility problem with "other" operating
systems.
Thanks for clarifications.
It makes sense in that case - I don't have any more questions ;)
