Slawek, forgive me if I take advantage of your patience.

Before rebooting nodes, I modified nodes and controllers with security groups logs, modifying neutron.conf, ml2 and openvswitch agents, moving from iptables_hybrid to openvswitch firewall etc etc.....

I only restarted neutron components and before rebooting nodes and controllers, I saw security groups logs and I was able to migrate instances.

Why after rebooting not ?

And, please, what about “multiple port bindings” ?

Thanks

Ignazio

Yes, In queens there wasn’t yet migration between various firewall drivers so that can be an issue. It should works fine since Rocky release with “multiple port bindings” feature.

Yes, logging isn’t supported by iptables_hybrid driver.
