Hi,
x-data-plane syntax is deprecated (should be remove in qemu 2.2),
it's using now iothreads
http://comments.gmane.org/gmane.comp.emulators.qemu/279118
qemu -object iothread,id=iothread0 \
-drive if=none,id=drive0,file=test.qcow2,format=qcow2 \
-device virtio-blk-pci,iothread=iothread0,drive=drive0
I don't now about the stability, but here what is working and I have tested:
-live migration
-resizing
-io throttling
-hotplugging
I think block jobs (mirror,backup,...) don't work yet.
it's working with virtio-blk and virtio-scsi support is coming for qemu 2.2
Regards,
alexandre

Objet: [Qemu-devel] is x-data-plane considered "stable" ?
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.
