Glance itself will default to non-durable queues (config opt rabbit_durable_queues), but there's code in Devstack that will attempt to match Glance's durability to that of an existing queue. Can you verify that the relevant code in Devstack is functioning correctly? See 'rabbit_durable_queues()' in lib/glance.
