It's time to commit to a final command-line interface: qemu -object iothread,id=iothread0 \ -drive if=none,id=drive0,file=test.qcow2,format=qcow2 \ -device virtio-blk-pci,iothread=iothread0,drive=drive0 The iothread= property associates a virtio-blk-pci instance with an IOThread. If the iothread property is not given, the non-dataplane code path is used. This means dataplane is not the default yet. The x-data-plane=on|off property is now obsolete but will be kept around for at least another release cycle to give users a chance to migrate.
