I followed the guide on hastexo to create an OpenStack Cloud. The Keystone service and the are supposed to run on separate machines. However, when I wanted to run glance-api in the console for debugging I had the following error:
ERROR: Unable to load glance-api-keystone from configuration file /etc/glance/glance-api-paste.ini. Got: ImportError('No module named keystone.middleware.auth_token',)
So the Glance API isn't running. I'm running Ubuntu 12.04 LTS and Openstack Essex.
