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 ----- Mail original ----- De: "Scott Sullivan" <ssulli...@liquidweb.com> À: qemu-devel@nongnu.org Envoyé: Jeudi 2 Octobre 2014 17:20:55 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.
