+
+The virtio-blk SCSI passthrough feature is a legacy VIRTIO feature. VIRTIO 1.0
+and later do not support it because the virtio-scsi device was introduced for
+full SCSI support. Use virtio-scsi instead when SCSI passthrough is required.
+
+Note this also applies to ``-device virtio-blk-pci,scsi=on|off'', which is an
+alias.
