I wrote a couple of articles on this: http://www.sandywalsh.com/2012/04/openstack-nova-internals-pt1-overview.html http://www.sandywalsh.com/2012/09/openstack-nova-internals-pt2-services.html and, to a lesser extent: http://www.sandywalsh.com/2012/10/debugging-openstack-with-stacktach-and.html More to come, thinking about tackling the HTTP layer next (unless people have other suggestions?)
