Hello all,
is there any way to make custom iptables rules persistent during host upgrade? I have for example zabbix agents installed on all hosts and thus iptables rule allowing connections from our zabbix server. Sadly = I have to manually restore iptables backup after host upgrade (initiated=
from oVirt manager).
This should be achievable by defining the iptables rules you wish to us= e when [re]installing using the engine-config tool:
thanks a lot for reply
1. Check the existing iptables rules: sudo engine-config -g IPTablesConfig
this displays whole iptables template. Interesting thing is that there=20 is a variable @CUSTOM_RULES@. Maybe custom rules could be defined this wa= y?
2. Define the desired iptables: sudo engine-config -s IPTablesConfig=3D"Your rules"
I entered... engine-config -s IPTablesConfig=3D"-A INPUT -p tcp -m state --state NEW -= m=20 tcp -s xx.xx.xx.xx --dport 10050 -j ACCEPT" =2E..and it looks like this overwrite entire IPTablesConfig template...
3. Verify the changes sudo engine-config -g IPTablesConfig
=2E..because this displays only just my one line above. I have copy of default template but I have no idea how to set this=20 variable with multi line text. I tried inserting \n but it is not=20 converted to newlines. Any ideas? Btw. these variables are stored in database? Thanks in advance, Jiri
4. Restart the engine for changes to take effect
5. Reinstall the host and verify the iptables rule.
And another question I have always wanted to ask... It looks like host=
upgrade is upgrading just vdsm components and no others virtualization= stuff
this was updatet after clicking to "host upgrade"

I believe qemu-img-rhev, spice-server, libvirt, mom,... are important components too. Should not be upgraded as well?
Thanks for clarification,
Jiri
