I'm in no way a ovirt expert. But as Linux administrator, I would say that firewalld and iptables are "front-end" to kernel internal security tables, so, in the final of the day, will provide *almost* same functionality.
Seems that firewalld is able to activate modules without restarting entire firewall infra-structure, which iptables is not capable of. This leverage an advantage for firewalld, specially where you would not have interruptions in existing stateful connections. I've used iptables *always* as replacement for firewalld because of almost 20 yrs using iptables - this is the first step in all about hundred Centos7 installations I've done past few years. I just can't throw away all my scripts that block hackers, provide 2 and 3 way "knock-knock" lockers, fail2ban customizations, nat rules, DMZ, and all, everytime a new "firewall" front end appears. I've seen at least two or three "iptables killers tech" in the past, and iptables still is the king - at least for me. Again, repeating myself, I'm no ovirt specialist. Just a sazonal linux admin which will not jump from iptables train yet. Perhaps, I would not reccomend to completely deactivate all firewall in any server! If it is the case, I would instead to advice to just replace firewalld with iptables-service (at least, in Centos7) - but only in case you have too much to loose without iptables (as am I).

It would make a lot easier the managing the firewall rules for me because of many automatisms I created based on iptables. Did anyone manage to do this? Any contraindication for doing this or precaution that I have to take care of?
