I'm trying to build a disk image following this doc https://github.com/openstack/heat-templates/blob/master/hot/software-config/elements/README.rst;
Instead of building a fedora image i'm trying to build a Centos disk
image. Unfortunately the build doesn't succeed and i'm incapable of
figuring out the reason. Can you please look at the output attached and
tell me whether you see something strange??
