Public bug reported:
In IceHouse something has changed in Glance and when I try to launch an
instance with option "create volume from image" it fails, because some
attributes are absent in image dict returned from Glance. Different types of
images were tried. RDO packages are used.

ok). If I add an owner to the image, then another attribute will also be
