Comment 1 for bug 1798241

Yep, this is broken.

Previously all transport url values had a '/' appended automagically by oslo.messaging. This causes the connection to be scoped to the default rabbit vhost "/".

Now if a transport_url is configured without a trailing '/' (e.g. rabbit://host:5672) oslo.messaging won't append the trailing /. This is a behavioral change.

For now a workaround is to add a trailing '/' to the transport_url configuration value.
