ImportError: No module named persistence.backends.sql

I am currently working on setting up OpenStack infrastructure on 3 nodes. I am stuck on starting keystone after I have successfully installed it. The error message I am getting is

ImportError: No module named persistence.backends.sql

The controller node has Ubuntu 12.04 and I am installing OpenStack icehouse version.. Could somebody shed some light on this error?

Solution

  • You would get that error if you used a keystone configuration file edited for the OpenStack Juno release with your Icehouse packages. In Icehouse, the correct value was "keystone.token.backends.sql.Token", only in Juno did it become "keystone.token.persistence.backends.sql.Token". [1]

    So, check your keystone.conf, make sure it is written for Icehouse.
