Can anyone tell me if in any QEMU release x-data-plane is considered "stable"?
If its unclear, I am referring to the feature introduced in QEMU 1.4 for high performance disk I/O called virtio-blk data plane. http://blog.vmsplice.net/2013/03/new-in-qemu-14-high-performance-virtio.html I've tried searching docs, but can't find any mention if its still considered experimental or not in the latest QEMU releases.
