The x- prefix means that the migration is still experimental; do we want to be codifying the use of experimental API into libvirt, or is it time for a patch to qemu to remove the x- prefix? Back in the 1.5 timeframe, when RDMA was first proposed, the x- prefix made sense, but now that we are closer to qemu 1.6, and you are trying to get libvirt to drive it,

That's a good question. I'll consult with the community for guidance. It has been very extensively tested, though - by several parties, but I'll find out and be in touch.
