Hi I would like to add rules into the iptables of the Hosted Engine VM in Ovirt. the version is oVirt Engine Version: 4.1.1.8-1.el7.centos I have tried using the normal process for iptables (iptables-save etc), but it seems that the file /etc/sysconfig/iptables this is ignored in the Ovirt Engine VM. How can I add permanent rules into the Engine VM? Kind regards Andrew
