commit 76a2f8b33e3f673b96feeb2724ae55567a3b6520 Author: Jakub Libosvar <[email protected]> Date: Wed Apr 29 11:15:36 2020 +0000 [ovn] Add PortBinding delete event for external ports The ports are unbound from chassis before they get deleted after VM with normal VIF ports is deleted. In case of SRIOV, we do not unbound the external SRIOV port but we delete it right away with chassis column set. This patch adds DELETE event type support to the event that tears down the metadata datapath. Also a warning is added if bound port that is not external is being removed.

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1875865 Title: SRIOV OVN metadata namespaces not cleaned up after ports are unbounded Status in neutron: Fix Released Bug description: Description of problem: See 'Steps to Reproduce' below. The external port is deleted from the port_binding table instead of chassis removed and then deleted so the PortBindingUpdate event is never generated. The metadata agent reacts on Port Binding Update event only. That means when there is a VM and we delete it, it first calls port update to remove the chassis from the port binding, so the port binding is chassis=[] before the PB gets deleted. In SRIOV scenario we don't do that and we delete a port that is bound. We need a special event for the sriov deletion case. Steps to Reproduce: 1. create an SRIOV port on either a tenant or a prov network + create a VM attached to that port - check ovn metadata namespace has been created on a GW node 2. remove that VM - the ovn metadata namespace is not removed from that GW node 3. even after removing the port, the namespace is not removed Actual results: OVN metadata namespaces clean up mechanism not working with SRIOV ports Expected results: Namespaces should be removed after port is removed To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/1875865/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : [email protected] Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
