true, still waiting on libvirt to allow access to system qemu

I am afraid that this will come inevitably :) Even if it worked, I can imagine people will complain that it isn't that much faster, doesn't work with Windows, is buggy with wayland etc.. We have to put pieces together and push people to do the required changes. Otherwise we are stuck, like for the past 6 months, and nobody even bother to test it..
