[libvirt-users] how to use virtio-blk-data-plane in libvirt

[Hui Kai Ran]

Hi,

I learned that there is a new technology - virtio-blk-data-plane 
introduced in qemu to bring a leap in IO performance to KVM. Has this 
feature been supported in libvirt? if it's, how to configure xml to 
support this feature?

thanks.
