...ented SCSI passthrough for the virtio-blk driver. Principle is quite simple, just put the missing fields (cdb, sense and status header) on the virtio queue and then call the SG_IO ioctl on the host. So when using '-drive file=/dev/sgXX,if=virtio,format=host_device' you can happily call any sg_XX command on the resulting vdX device. Quite neat, methinks. And it's even backwards compatible, so each of these patches should work without the other one applied. As one would have guessed there are two patches, one for the linux kernel to modify the virtio-blk driver in the guest and one for...
