Perhaps you could add the iptables and firewalld packages to yum.conf as ex=
cludes. I don't know if this would fail silently=2C but if so=2C the engin=

New subject: [Users] Otopi pre-seeded answers and firewall settings
Giuseppe,
I should have clarified. I meant to blacklist the packages only for a
short time, while you add the nodes to the oVirt environment. Once
everything was set up, you would remove these restrictions and yum install
iptables. You'd then configure to taste.
Glad to hear of your success with the conf file method, though.
Thanks,
Joshua
