[ovirt-users] Safely disable firewalld [Ovirt 4.3]

Hi all, I was wondering if it's "safe" disabling entirely the firewalld service and manage the firewall only via iptables, on the host and on the hosted engine (a self-hosted engine). 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? Thanks for your time and help, Francesco
