compute node? Or did you also change the rabbitmq configuration? The <br>
transport_url should match the actual rabbitmq config, of course, and <br>
it should be the same on every node.<br>
Does that match your cell setup? To compare run:<br>
<br>
control:~ # nova-manage cell_v2 list_cells --verbose<br>
<br>
Do you have a vhost configuration? (I'm not familiar with devstack)<br>
Here's an example of a "nova" vhost with respective permissions:<br>
<br>
<br>
control:~ # rabbitmqctl list_vhosts<br>
Listing vhosts<br>
/<br>
nova<br>
<br>
control:~ # rabbitmqctl list_permissions -p nova<br>
Listing permissions in vhost "nova"<br>
nova .* .* .*<br>
<br>
<br>
If there's a vhost it should be also reflected in the transport_url. <br>
Maybe you should share all of the above information here.<br>
