Thanks, the whole iSCSI LUN have been passed to the VM.
But I test it with scsicmd, and found that the driver may be not
support SPC-3, but if i use this by microsoft iscsi initiator, I can
pass all the scsi3_test tests.
If you are passing the LUN to the VM with device='lun', the driver and
VMM do not interpret any SCSI command. You should see exactly the same
data as in the host, which includes support for SPC-3:

Can you try using a Linux VM and executing sg_inq in the VM?
