Thank you Didi.
The proposed method works. I described my experience here: https://blog.it-kb.ru/2016/11/24/extension-of-iptables-add-custom-rules-on-t...
Thanks for this post, and the report! (although I can't read Russian). Best,

How?
I am not sure I understand the question.
The same way you configure iptables on non-oVirt-hosts machines.
If you mean "How to imitate the way the engine does this during host deploy", then I don't know - you can check engine sources for that. I am guessing that you can get the values of IPTablesConfig and IPTablesConfigSiteCustom with engine-config, replace inside the latter "@CUSTOM_RULES@" with the contents of the former, then copy the result to the host and load it with iptables-restore (and/or copy to /etc/sysconfig/iptables and restart iptables service).

Hi Didi!

"Move to maintenance and reinstall" to add the iptables rules ?
Are you serious?
There is no other way (without reinstalling the hosts) ?
AFAIK, using ovirt-host-deploy, no.
I am not aware of an engine API or vdsm verb to do this, but these are not my main area of expertise.
As I wrote there, you can also do this manually.
The oVirt engine is not a replacement for configuration management systems. If you have complex needs, might as well uncheck this checkbox and use other means.
Best,

Please check the other thread here "[ovirt-users] Hook to add firewall rules". Thanks.
