This document describes ADV, an architecture for managing large numbers of similar computer clients in classrooms. ADV allows administrators to clone, deploy, manage, and modify operating systems on clients. It was developed by universities in Spain to deploy and customize a variety of operating systems. ADV includes client, server, and API components to manage offline and online clients through PXE booting, imaging, and a web interface. Future plans include integrating with other university projects and releasing version 1.0.
