Comment 15 for bug 1860021

I believe current issue:
nova.exception.ImageUnacceptable: Image 9c9cd2a3-4615-4470-b90b-3125fa6d8a7f is unacceptable: Image is not raw format

is different from the one reported which *was* fixed. We already verified that. Now we are running in circles and there are many issues plaguing that job.
