Can somebody knows how to enable virtio-scsi-data-plane in libvirt for specific domain? I know that i need to replace "-device virtio-scsi-pci" with "-object iothread,id=io1 -device virtio-scsi-pci,iothread=io1" in qemu, but how can i do this in libvirt?

Yes, thanks! Does in near feature libvirt devs integrate this ability to domain format? As i understand all qemu stable features supported by libvirt. And data plane for virtio-blk is stable for some time....
