Hi,

I followed the video and the steps provided in this video link and the consumer connection is being refused.

https://www.openstack.org/videos/summits/denver-2019/nova-versioned-notifications-the-result-of-a-3-year-journey

/etc/nova/nova.conf file changes..

[notifications]

notify_on_state_change=vm_state

default_level=INFO

notification_format=both

[oslo_messaging_notifications]

driver=messagingv2

transport_url=rabbit://guest:guest@10.30.8.57:5672/

topics=notification

retry=-1

The python consume code is as follows (followed the example provided in the video:

transport = oslo_messaging.get_notification_transport(
            cfg.CONF, url='rabbit://guest:guest@10.30.8.57:5672/')
targets = [
    oslo_messaging.Target(topic='versioned_notifications'),
]

Am I missing any other configuration in any of the services in OpenStack?

Let me know if you need any other info.
