Hallo all, Our cloud setup was migrated to Havana and the nova-manage version in the controller node is 2013.2. In the compute node, the nova-manage version is 2013.2.2. I am getting an error in the nova-compute log that describes "IncompatibleObjectVersion: Version 1.9 of Instance is not supported". The compute service is stopped and I am unable to start it again. Can anybody help me to solve the problem? Regards, Krishnaprasads -------------- next part -------------- An HTML attachment was scrubbed...
