If you load the 'sg' module under linux, you'll get a /dev/sgX entry for
each scsi device (sd, st, etc) which is used to be able to send raw scsi
commands to devices.

If you wanted to pass raw disks to domains then pvscsi could do that,
but I can't speak from a performance point of view as I haven't tried
it. There could be less overheads involved... You also wouldn't be able
to boot from them as I don't believe that the HVM bios can boot from raw
scsi disks.

Jun posted the latest pvscsi patches to the xen-devel list on Friday
30th, you should be able to find them in the mailing list archives.
