Hi Kate, You were right. The bug I referred to does not block the engine. So when I looked at the engine log, this is what I see after trying to deploy an environment with the HOT package I attached in my earlier message: http://paste.openstack.org/show/481260/ I looked up the error message and realized that the "Core library" package was missing in my environment. So I uploaded it and now the deployment seems to work fine. Thanks for your help. Regards, --Vahid -------------- next part -------------- An HTML attachment was scrubbed...
