Briefly tested with SPDK target via bdevio through both vhost-user and QEMU's virtio-pci. vhost-blk driver is not mentioned in any doc yet. A virtio-blk bdev can be created as following: `construct_virtio_user_blk_bdev /tmp/virtio.0 MyVirtioBlk0 --vq-count 16` `construct_virtio_pci_blk_bdev 0000:01:00.0 MyVirtioBlk1` or ``` [VirtioUser0] Path /tmp/vhost.0 Type Blk Queues 16 [VirtioPci] Enable Yes ``` If `Type` field is not present, the VirtioUser section will be parsed as a SCSI one, preserving backward compatibility.
