Sandro Bonazzola has submitted this change and it was merged. Change subject: upgrade: prevent deploying additional 3.6 host on a 3.5 setup ...................................................................... upgrade: prevent deploying additional 3.6 host on a 3.5 setup Deploying an additional 3.6 hosted-engine host requires an existing 3.6 system. Mixing 3.6 and 3.5 hosts in the same HE cluster is not supported: in order to deploy a new 3.6 host, the user has to update existing hosts to 3.6, and only then add the new host. Looking for the presence of the configuration image uuid in the answerfile, we can detect if the answerfile is from 3.5 or 3.6, and warn the user if needed.
