Hi
I would like to add rules into the iptables of the Hosted Engine VM in
Ovirt.
I am wanting to monitor the Ovirt Engine using Nagios -> NRPE and I would
like to open port 5666
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
is ignored when the Ovirt Engine VM starts.
What do you mean in "ignored"?
What's the output of 'iptables-save'?
Did you ask to configure the firewall during engine-setup?
How can I add permanent iptables rules into the Engine VM?
On the engine vm (unlike hosts), the only thing that touches iptables
is engine-setup. Before doing that it asks you if you want to configure
the firewall. There aren't currently means to add your custom rules -
either you manage it all by yourself or you let engine-setup do that.
Alternatively, it's recommended to use firewalld. engine-setup can
add to firewalld the stuff it wants, and you still can add your own
stuff.
If I got you wrong and you refer to the hosts (not engine), see also:

Best,
Kind regards
