Are you planning on allowing the export of only a single device, eg if
the SCSI bus was like this:

#0 - SCSI Disk
#1 - SCSI Disk
#5 - SCSI CDROM
#6 - SCSI Tape
#7 - SCSI HBA

Could I export #5 to one domain, #6 to another domain, and use #0 and #1
in Dom0? Maybe your code already can do this?

/dev/sgX is the SCSI Generic interface, and it is available in
userspace.

Thanks
