Someone said that it is because the kernel option CONFIG_XEN_DEV_EVTCHN should be set as 'y' but not 'm', so I checked my linux kernel configuration, and found it is set as 'y'.
 
I can find /sys/bus/scsi/devices/host0/target0:0:0:0/0:0:0:0/vendor, or /sys/bus/scsi/devices/host0/target0:0:0:0/0:0:0:0/scsi_device/0:0:0:0/device/vendor, but definitely no  /sys/bus/scsi/devices/host0/vendor
 
Why this happen? And how can I fix this?
 
Thanks.
