Description of problem: In 4.1 cluster compatibility level, firewalld is default firewall type, while 4.1 hosts do not support it. Version-Release number of selected component (if applicable): ovirt-engine-webadmin-portal-4.2.1.2-0.1.el7.noarch How reproducible: 100% Steps to Reproduce: 1. Create new DC and cluster 2. Set compatibility level to 4.1 on cluster 3. Check default firewall type Actual results: firewalld Expected results: iptables
firewalld support was introduced by the Infra team, moving the (surprising) bug to them.
So again firewalld doesn't depend on cluster level, but on VDSM version installed, more info in original bug *** This bug has been marked as a duplicate of bug 1517538 ***
