Github user remibergsma commented on the issue: https://github.com/apache/cloudstack/pull/1934 What about signed S3 urls that people may supply? If you want to register a template and have it download from a S3 bucket, you need to specify a signed url to provide the authentication. But that signature is valid for either GET or HEAD requests, not both. When you use S3 as secondary storage, you automatically get a GET pre-signed url from CloudStack that you cannot use to register it as a new template. Something to think about.. See: http://stackoverflow.com/questions/15717230/pre-signing-amazon-s3-urls-for-both-head-and-get-verbs
