I had the same issue. My problem was that all the configuration that was supposed to be under the "[keystone_authtoken]" section in the glace-registry.conf file, ended up under the "[matchmaker_redis]". I guess I got confused by all the comments in that file. Fixed the config, restarted the glace-registry and glance-api services and then I was able to retrieve the images using the "nova image-list" command.
