Checkpointing virtual machines shows potential for allowing a user to download, install, and initialize a complete software environment by selecting a web page link. Starting with the open source User-Mode Linux project, we added checkpointing functionality and integrated the standard xdelta and curl utilities to handle compression, expansion, and download. The current system allows researchers and others to configure Linux-based software demonstrations in detail and save them as snapshots that can be as small as a few megabytes. Users can then easily replicate every detail of the demonstrations without worrying about compilation, installation, dependencies or initial setup.
