OpenNebula/one-apps — reverse-engineered prompt

Build me a toolset for creating OpenNebula cloud appliances.

I want it to help package guest contextualization for both Linux and Windows, so new virtual machines can automatically set up networking, users, SSH keys, and run startup scripts from OpenNebula context data. It should also include image build scripts that can produce ready to use qcow2 Linux images with the contextualization already included.

Please include support for the main appliance types this project is meant to build, especially the Virtual Router appliance and the OneKE Kubernetes appliance. The end result should feel like a maintainable command line build project, with clear make commands or simple scripts, sensible config files, and documentation that explains requirements, how to build artifacts, and where the outputs go.

Keep it practical for an OpenNebula admin who wants repeatable marketplace style appliance builds. Look up the current OpenNebula and Packer docs online if you need to.
