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
