Yes, that's correct. But it should be harmless - libvirtd will try
calling "firewall-cmd --state", fail because it doesn't exist, then fall
back to using iptable/ebtables directly.

Definitely try it out and let us know if it causes any trouble though.
Part of the reason of push it now is so that it can get a reasonable
shakeout between now and the next release.
