Open Stack

Hi Guilherme,

The RabbitMQ has virtual host for many applications. Default, the Rabbit 
created a default virtualhost with /.

You can see this with the command:

root at controller:~# rabbitmqctl list_permissions
Listing permissions in vhost "/" ...
guest    .*    .*    .*
...done.

Regards,

Marcelo Dieder
