Attaching a 3rd one for squashing as well -- it adds the scsi bus & disk
drivers, so that you can actually use the virtio-scsi HBA for something.
(The protocol chain is [VirtioScsiDxe] -->
gEfiExtScsiPassThruProtocolGuid --> [ScsiBusDxe] -->
gEfiScsiIoProtocolGuid --> [ScsiDiskDxe] --> gEfiBlockIoProtocolGuid.)
Once these are included, you can specify, for example, a SCSI CD-ROM:
-drive id=cd0,if=none,format=raw,readonly,file=xxx.iso \
-device virtio-scsi-device,id=scsi0 \
-device scsi-cd,bus=scsi0.0,drive=cd0
(edk2 will recognize the scsi cd-rom, but you'll only get a filesystem
on top if the ISO contains El Torito "stuff" that is appropriate for
UEFI booting.)
Thanks
Laszlo
