Hi Lars - Sounds like you're really looking for a conceptual understanding and I like that! Keystone does maintain the service catalog, and the Image service (glance) needs specific entries. See http://docs.openstack.org/essex/openstack-compute/install/yum/content/keystone-concepts.html. I believe glance_host and glance_port are deprecated and not needed in an Essex installation, use only glance_api_servers in the nova.conf. Gabe has good answers for your previous questions - and hopefully you can reference this page for Qpid configuration information: http://docs.openstack.org/essex/openstack-compute/admin/content/configuration-qpid.html Anne On Fri, Jun 15, 2012 at 3:26 PM, Lars Kellogg-Stedman <lars at seas.harvard.edu> wrote: > Well, apologies for the stupid subject line.
