And additional work to do this exists in Oz:
Which is used in the Image Factory project:
However none of these tools use Nova to manage the install containers.
That is the primary point of the demonstration code I've posted. I'm
unaware of any other tool that does this.
Both Oz and VeeWee could, in theory, be enhanced to support OpenStack
instances as another virt provider in which to perform installs using
the approach we're demonstrating here.

As far as I can tell Vagrant has a hard requirement for working base
images as input. It does not attempt to build base images from scratch,
they must be provided. In that sense it seems similar to
Tools like VeeWee and Oz (and potentially a builder based on our
demonstration) can provide this base input.
