Actually, I would prefer if more "light" kvm users (no demanding
performance requirements, no dependency on qemu-kvm-only features)
consider upstream instead of qemu-kvm so that it gains way more testing
than just by us when pushing some more bits. So we should keep on
informing people about limitations and known issues. We need them on
both sides.
