I unplug vnic / change ovn network of vms to the old one with port securty enabled / plug vnics again and they don't communicate. Questions: - what is the role of the "Network port security" option for an OVN network? - what is the meaning of "Undefined" option for it other than "Enabled" and "Disabled"? - it seems I cannot edit the value for "Network port security" option of an existing OVN network, is it correct? Thanks again, Gianluca
