[ovirt-users] Minor issue upgrading to 4.2

I upgraded a CentOS 7 oVirt 4.1.7 (initially installed as 3.5 if it matters) test oVirt cluster to 4.2.0, and ran into one minor issue. The update installed firewalld on the host, which was set to start on boot. This replaced the iptables rules with a blank firewalld setup that only allowed SSH, which kept the host from working. Stopping and disabling firewalld, then reloading iptables, got the host back working. In a quick search, I didn't see anything noting that firewalld was now required, and it didn't seem to be configured correctly if oVirt was trying to use it. -- Chris Adams <cma@cmadams.net>
