OpenStack Diskimage Builder

Diskimage-builder is a tool for automatically building customized operating-system images for use in clouds and other environments. It supports images from many major distributions and can produce cloud-images in common formats (qcow2, vhd, raw), as well as bare-metal filesystem images and ram-disk images. The images are assembled from included elements and the tool acts as a framework to easily add your own elements for further customization; it is used extensively by the TripleO project and within OpenStack Infrastructure.
