This patch adds a library, application and test scripts for extending SPDK to present virtio-scsi controllers to QEMU-based VMs and process I/O submitted to devices attached to those controllers. This functionality is dependent on QEMU patches to enable vhost-scsi in userspace - those patches are currently working their way through the QEMU mailing list, but temporary patches to enable this functionality in QEMU will be made available shortly through the SPDK github repository.
