You are using virtio-blk with SCSI-passthrough, not virtio-scsi (it's confusing but libvirt type='block' device='lun' means virtio-blk). This feature has fallen out of favor and is generally best replaced with virtio-scsi instead of virtio-blk. If you do not require raw SCSI commands from the guest, then change device='lun' to device='disk'. What exactly are you trying to do? Stefan
