From a8acc52e37d5a74487b0a787bf8a519debc3a031 Mon Sep 17 00:00:00 2001 From: Dumitru Ceara Date: Thu, 2 Apr 2020 10:35:32 +0200 Subject: [PATCH] ovn-controller: Skip vport bindings done through OVS external_ids:iface-id. Port bindings of type "virtual" should not have an associated OVS port in the integration bridge. If this is the case, it's a misconfig and ovn-controller should ignore it. If such a situation is detected, ovn-controller will also log a warning message to inform the user about the wrong configuration.
