Comment 2 for bug 800843

Peter: My original bug report may have been a bit misleading. Glance has an image attribute called 'checksum'. You can query glance directly and get that back (from the api) as X-Image-Meta-Checksum. Nova was doing some bad mapping of attributes that presenting checksum as a property (a.k.a user-defined metadata). This bug was just about changing that presentation logic in Nova.
