Comment 6 for bug 1792674

nova console-log works, which pops up logs of instances starting.

While do you mean openstack-nova-novncproxy.service ? yes, it's running
and listening on port 6080

There is no nova-consoleauth service running on Centos7.

I check every queue, there isn't any message.

Thanks.

Sent by: <email address hidden>

A messaging timeout usually indicates that the service that is meant to be
consuming the messages is not working.

Do other operations like "nova console-log" work?
Are there queues with messages that aren't being consumed (check rabbit
admin interface)?
Also is the nova-consoleauth service running ok?
