You are correct, deleted images are not deleted from the DB, rather their row has ‘deleted=1’, so specifying the UUID of another image already in glance for a new image being upload will end in tears.
What I was trying to convey was, when Christian is uploading a new image of the same name as an existing image, the UUID will be different. IMO, the correct process should be: 1. Make desired changes to your image. 2. Rename the existing image (e.g. Fedora-20-OLD) 3. (optional) Make the old image private ( is-public 0 ) 4. Upload the new image using the desired name (e.g. Fedora-20 or like Fedora-20-LATEST ) Obviously I assume there was testing for viability of the image before it was uploaded to glance. For more information, be sure to catch my talk on Tuesday 9am at the summit.
