OpenNebula

I've been reading the docs here: http://opennebula.org/documentation:rel4.0:suns_advance and have a few extra changes that I had to make to get sunstone up and running under passenger/apache:

1. Group ownership for config/auth files to allow read access (as per docs)
   chgrp www-data /etc/one/sunstone-server.conf
   chgrp www-data /etc/one/sunstone-plugins.yaml
   chgrp www-data /var/lib/one/.one/sunstone_auth

1. Execute permission to the parent directories for www-data to 'get to' sunstone_auth
   chmod a+x /var/lib/one
   chmod a+x /var/lib/one/.one

1. Write permissions for logging:
   chgrp www-data /var/log/one/sunstone*
   chmod g+w /var/log/one/sunstone*
