openstack - ImportError: No module named persistence.backends.sql -

i working on setting openstack infrastructure on 3 nodes. stuck on starting keystone after have installed it. error message getting is

importerror: no module named persistence.backends.sql

the controller node has ubuntu 12.04 , installing openstack icehouse version.. shed lite on error?

you error if used keystone configuration file edited openstack juno release icehouse packages. in icehouse, right value "keystone.token.backends.sql.token", in juno did become "keystone.token.persistence.backends.sql.token". [1]

so, check keystone.conf, create sure written icehouse.
