I, too, like the idea of shedding off the attempt to configure custom
iptables rules. Moving to firewalld makes it much easier to manage
such customization out of oVirt. (Anybody who's ever edited iptables
chains by hand would know what I mean)

Please note that what you describe is Leon's alternative (2.). Where
Vdsm, as oVirt host agent, has complete responsibility on configuring
the services needed by oVirt. There is no Engine/Vdsm interaction in
alternative (2.). Option (3.) requires Engine to provide a list of
services to the host.
