As the error said, you need to see the disk_format and container_format.
I haven't digged the code, but I think you should try to set the
container_format and disk_format when you create the image like this:
image = self.glance.images.create(name="myNewImage",
refer to: glance client Python API v2
http://docs.openstack.org/developer/python-glanceclient/ref/v2/images.html
add_location(image_id, url, metadata)
Add a new location entry to an image’s list of locations.
It is an error to add a URL that is already present in the list of locations.
