I too had this issue, however it seems to be related to Keystone endpoints. As a test I switched from using the MySQL DB for the endpoints to using the template file.
Change /etc/keystone/keystone.conf: [catalog] #driver = keystone.catalog.backends.sql.Catalog driver = keystone.catalog.backends.templated.TemplatedCatalog template_file = /etc/keystone/default_catalog.templates I then restarted keystone and apache2. When I navigated to instances and volumes I was now able to get to the page with no issue. After this I changed back to using MySQL and tried to create an endpoint based off of what I noted in the template file. Restarted services again, but it still failed. It is my guess that I'm not using the correct syntax to create the endpoint or there is something within the URLs being passed that is not working correctly. Any comments from some keystone experts would be welcome at this point. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to nova in Ubuntu. https://bugs.launchpad.net/bugs/995079 Title: Internal server error when accessing nova/instances_and_volumes/ via horizon To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nova/+bug/995079/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
