At first glance, this seems to be a nova bug since it's responsible for creating images and then `uploading` them to `glance-api`. In this whole process, glance does not modifies the image at all. What makes you think this is a Glance bug? Any detail that I could be missing?
I opened on glance because I thought that the image would be created with glance and not nova (nova will call glance). but if not, please change component to nova :)
Hey, I couldn't locate this bug in nova component and took the liberty of creating it. I didn't know it was already filled against glance ;) Closing as a duplicate because the other one contains more information. *** This bug has been marked as a duplicate of bug 1026325 ***
