> Thanks for your reply. Can I kindly know should I upgrade or downgrade the nova version? If you start from scratch I would certainly run the latest version. Quite a few bug fixes in 2013.2.2: https://wiki.openstack.org/wiki/ReleaseNotes/2013.2.2 There are reasons to stick to an older version though. (e.g. it currently works, there is nothing in the release notes we need, so lets not break it ;) Cheers, Robert van Leeuwen
