Hi Didi, many thanks for your invaluable help! I'll try your suggestion (/etc/ovirt-host-deploy.conf.d/99-prevent-iptables.conf) asap and then I will report back.
By the way: I have a really custom iptables setup (multiple separated networks on hypervisor hosts), so I suppose it's best to hand tune firewall rules and then leave them alone (I pre-configure them, so the setup procedure won't be impeded in its communication needs anyway AND I will always guarantee the most stringent filtering possible with default deny ecc.).

Full logs attached. I resurrected my Engine by rebooting the (still only) host, then restarting ovirt-ha-agent (at startup the agent failed while trying to launch vdsm, but I found vdsm running and so tried manually...). OK, so it's host-deploy that's doing that.But it's not host-deploy itself - it's the engine that is talking to it, asking it to configure iptables.I don't know how to make the agent don't do that. I searched a bit the sources (which I don't know)and didn't find a simple way. You can, however, try to override this by:# mkdir -p /etc/ovirt-host-deploy.conf.d# echo '[environment:enforce]' > /etc/ovirt-host-deploy.conf.d/99-prevent-iptables.conf# echo 'NETWORK/iptablesEnable=bool:False' >> /etc/ovirt-host-deploy.conf.d/99-prevent-iptables.conf Never tried that, and not sure it's recommended - if it does work, it means that host-deploy will notupdate iptables, but the engine will think it did. So it's better to find a way to make the engine not dothat. Or, better yet, that you'll explain why you need this and somehow make the engine do what you want...-- Didi
