Hi,

Sorry, I forgot to show usage of the "xend". I will describe it below.


1.) Configuration FIle
#-----------------------------------------------------------------------------
#   Configure PVSCSI devices:
#
#vscsi=[ ''PDEV, VDEV'' ]
#
#   PDEV   gives physical SCSI device to be attached to specified guest
#          domain by one of the following identifier format.
#          - XX:XX:XX:XX (4-tuples with decimal notation which shows
#                          "host:channel:target:lun")
#          - /dev/sdxx or sdx
#          - /dev/stxx or stx
#          - /dev/sgxx or sgx
#          - result of ''scsi_id -gu -s''.
#            ex. # scsi_id -gu -s /block/sdb
#                  36000b5d0006a0000006a0257004c0000
#
#   VDEV   gives virtual SCSI device by 4-tuples (XX:XX:XX:XX) as 
#          which the specified guest domain recognize.
#

#vscsi = [ ''/dev/sdx, 0:0:0:0'' ]


2.) Command
    ''scsi-attach''  :  (''<Domain>
<PhysDevice> <VirtDevice> [BackDomain]'',
                        ''Attach a new SCSI device.''),
    ''scsi-detach''  :  (''<Domain>
<VirtDevice>'',
                        ''Detach a specified SCSI device.''),
    ''scsi-list''    :  (''<Domain>
[--long]'',
                        ''List all SCSI devices currently
attached.''),
