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 declaration of stability. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
