I am trying to setup a fresh juno openstack environment (1 controller-node, 1 network-node and 1 compute-node). Everything works fine except instance creation.

Seeing following message in the log file

    **IncompatibleObjectVersion: Version 1.9 of InstanceList is not supported**

-controller-node and compute-node are on same nova version (2.19.0)

did the following tasks as part of troubleshooting. still the issue persists. -executing "nova-manage db sync" on the controller -delete and recreate nova DB, as well as remove & reinstall of all nova packages on both controller-node & compute-node

Edit your question, explain how you installed openstack: maybe some broken package?

That's simple configuration. Install RDO Juno via packstack multi-node answer-file wouldn't have any problems with package consistency.

Hey hi, as per the OpenStack documentation-- each service has its set of objects, each with a version attached. When a client attempts to call an object method, the server checks to see if the version of that object matches (in a compatible way) its object implementation. If so, everything is fine, and if not, raises an exception. My suggestion for you is,

  1. If possible, try to upgrade/downgrade the versions of nova services.
  2. Try to sync database version with nova services.
