Hi Zhangfei,
I am also interested in pscsi, you can try kvm, seems you can create a
virtualized pscsi device in kvm / virt-manager. I haven't tried that
yet, hope this can help.
Thanks,

I am testing with pscsi, but fail to find any block device under /dev to mount.
The scsi_probe_lun seems can not return correctly, scsi scan: INQUIRY failes.
Is this usage correct?
/backstores/pscsi> create name=pscsi_backend dev=/dev/sdb
Note: block backstore recommended for SCSI block devices
Created pscsi storage object pscsi_backend using /dev/sdb
/backstores/pscsi> cd /vhost
