Doc Text:	Before, a REVERT_RESIZE operation could fail if using the iptables_hybrid firewall driver. This would happen due to Neutron sending the network-vif-plugged external event before Nova starts to listen for it. Now, Nova will start listening for network-vif-plugged external event based on the characteristics of the port. In the case of an OVS hybrid plug, it will start listening before sending the port binding request to Neutron.	Story Points:	---

Comment 15 Filip Hubík 2019-08-20 08:32:57 UTC

Since this issue is flaky, I started with continuous testing to be sure this is really fixed. It will take several days to complete. So far CI shows improvement, but we don't have enough Tempest runs yet.

Comment 16 Filip Hubík 2019-08-21 09:02:03 UTC

After 100 runs of Tempest test series (~5hrs)

tempest.api.compute.servers.test_server_actions.ServerActionsTestJSON.test_resize_server_revert_with_volume_attached
tempest.api.compute.servers.test_server_actions.ServerActionsTestJSON.test_resize_server_revert

and I do not see this issue happening again. It is also supported by the results from CI where this error disappeared landing openstack-nova-*-18.2.1-0.20190509150817.8e130e2 packages in containers (that's why I also bumped the fixed in version here).

Tested on virthost topology 3 controllers/2 compute/3 ceph nodes/ipv4/vlan deployed by InfraRed.
