This will get squashed in with the conf patch. I'll also generate the
news.html.in entry:

          <li>vhost-scsi: Add support scsi_host hostdev passthrough<br/>
          Add the capability to pass through a scsi_host HBA and the
          associated LUNs to the guest.
          </li>


ACK -

I'll push these in a bit, just seeing what I get on my test system... Of
course I'm also curious what would happen if I try to pass through a
vHBA ;-)...
