similar to: virtio scsi host draft specification, v3

Hi all, here is the specification for a virtio-based SCSI host (controller, HBA, you name it). The virtio SCSI host is the basis of an alternative storage stack for KVM. This stack would overcome several limitations of the current solution, virtio-blk: 1) scalability limitations: virtio-blk-over-PCI puts a strong upper limit on the number of devices that can be added to a guest. Common

Hi Rusty, here is the specification for a virtio-based SCSI host (controller, HBA, you name it) so that you can apply it to the spec document and publish it. I changed the index from 7 to 8 to account for the rpmsg device, and added a feature bit to tell the guest in advance whether the host supports hotplug. Otherwise there is no change from v2.
