Are you proposing a solution or just raising an issue? 
<div><br>
</div>
<div>I did find it strange that kolla-ansible doesn't support HA queue by default. That is a disaster because when one of the nodes goes down it will make the whole rabbitMQ unacceptable. Whenever i deploy kolla i have to add HA policy to make queue HA otherwise
 you will endup in problem. </div>
