Using a the Xen Hypervisor to Supercharge OS Deployment

Hypervisor technology presents some promising opportunities for optimizing Linux deployment. By isolating a server's unique properties into a set of patches to initialization scripts and other selected files, deployment of a new server will be demonstrated to occur in a few seconds by creating a new Xen domain, re-using an existing file system image and applying patches to it during domain initialization. To capture changes to a server's configuration that occur while it is running, the paper discusses the potential of copy-on-write file systems to hold changes to selected files. By separating the initialization and file data that make a linux server instance unique, that data can be stored and retrieved in a number of ways.
