If you want to have the installation update packages, you'll
need to register the system log in to rhn and subscribe to an
available subscription.
export DIB_RHSM_USER to your rhn username
export DIB_RHSM_PASSWORD to your rhn password
To get the qcow2 image, log into rhn.redhat.com and download the
image from
https://rhn.redhat.com/rhn/software/channel/downloads/Download.do?cid=16952
Then export DIB_CLOUD_IMAGES to whereever you're hosting the qcow2.
