Hi Paul, yes, I did the same last week. A host reinstall is required. When you have some custom rules for IPtables, you can also add custom rules to firewalld via ansible: In eninge shell, go to /etc/ovirt-engine/ansible/ and copy the example file to same dir without example and add your necessary rules there. I had to add one for zabbix agent: - name: Enable zabbix port on firewalld firewalld: port: "10050/tcp" permanent: yes immediate: yes state: enabled Save and run reinstall on host, no engine service restart is required.

"Cluster Default uses IPTables firewall, which has been deprecated in 4.2 of the engine, and will no longer be supported starting with version 4.3. Make sure to switch to Firewalld before upgrading to 4.3." If the correct way to change to firewalld edit cluster, and run reinstall?
