The scsi command is 0x51.
see page page 91:

Curious if anyone has any information on this, an idea of if it would be implemented, or when if ever.
If it won't be implemented, it would be important also.

Please check that this issue is still present. If yes, please post more information about your configuration (exact QEMU version, qemu command-line, guest OS and version).
