Do you use this as a "all-in-one" devstack or do you add a new node to an existing multi-node environment? If you have a multi-node environment, could you please check which versions the services on the nodes have?

[Devdatta Kulkarni (devdatta-kulkarni)]

@markus_z: I am using all-in-one devstack.

[Markus Zoeller (markus_z) (mzoeller)]

@Devdatta: Could you attach your "local.conf" file here or paste it to http://paste.openstack.org/ please? Could be something with the "upgrade_levels" config options. Maybe they are pinned to an older version.
