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 ;-)... John
