The virtio-scsi HBA is the basis of an alternative storage stack for QEMU-based virtual machines (including KVM). Compared to virtio-blk it is more scalable, because it supports many LUNs on a single PCI slot), more powerful (it more easily supports passthrough of host devices to the guest) and more easily extensible (new SCSI features implemented by QEMU should not require updating the driver in the guest).
