How much of a problem is this, since there are caps checks? (assuming the interface in qemu doesn't change - I don't think it will).

We were aiming for fedora 24 if possible, but I see qemu 2.6 is planned for 04-26, which is a week after Fedora code complete deadline 04-19. It's a bit sad to delay by >2 months given that Spice support is now finally ready. Many people are eager to have accelerated VMs in virt-manager, I wonder what solution we can find to shorten the delay.
