The x-data-plane=on|off option is no longer useful because the iothread=<iothread> option conveys the same information plus which IOThread to use.
Do not delete x-data-plane=on|off yet as a convenience to people using this legacy experimental option. We will drop it in QEMU 2.2. Instead, turn on data-plane when either x-data-plane=on or iothread=<iothread> are used. The following command-line uses data-plane: qemu -device virtio-blk-pci,iothread=foo,drive=drive0 Signed-off-by: Stefan Hajnoczi <stefa...@redhat.com> --- hw/block/dataplane/virtio-blk.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/hw/block/dataplane/virtio-blk.c b/hw/block/dataplane/virtio-blk.c index f6e1a5d..4c5ba18 100644 --- a/hw/block/dataplane/virtio-blk.c +++ b/hw/block/dataplane/virtio-blk.c @@ -132,7 +132,7 @@ void virtio_blk_data_plane_create(VirtIODevice *vdev, VirtIOBlkConf *blk, *dataplane = NULL; - if (!blk->data_plane) { + if (!blk->data_plane && !blk->iothread) { return; } -- 1.9.3
