@baluchen ,

Before restarting your VM please try and do ./unstack.sh.

Depending on your system configuration, your Horizon dashboard is not fully operational because some services might not have been started. The following is valid for Ubuntu 14.04 VM:

If you don't manage to login at all with the error: "Error: An error occurred authenticating. Try again later."

• You must start Keystone services: $ keystone-all

If you do not get information on resources upon accessing Horizon you should check that Nova, Glance, Cinder are active:

• E.g. start Glance (you may need sudo privileges): $ glance-control all start

If Horizon is not accessible at all:

• Check Apache2 service and start it if not running (you may need sudo privileges): $ service apache2 start Check Django server is running (locate Horizon code, usually at: /opt/stack/horizon): $ python ./manage.py runserver

Finish with ./rejoin-stack.sh on devstack directory.

This should do the trick. Please give it a try and let know of further barriers. It's unusual to have services like RabbitMQ not starting but any google search should be enough to find the remaining sweet spots.
