Virtual machines (VMs) are an increasingly ubiquitous feature of modern computing, yet the interested student or professional has limited resources to learn how VMs work. In particular, there is a lack of "hands-on" exercises in constructing a virtual machine monitor (VMM, or hypervisor), which are both simple enough to understand completely but realistic enough to capture the practical challenges in using this technology. This paper describes a set of assignments to extend a small, pedagogical operating system (OS) to form a hypervisor and host itself. This pedagogical hypervisor, called HOSS, adds roughly 1,000 lines of code to the MIT JOS source, and includes a set of guided exercises. Initial results with HOSS in an upper-level virtualization course indicate that students enjoyed the assignments and were able to apply what they learned to solve different virtualizationrelated problems. HOSS is publicly available.

“…However, LKMs provide a narrow view of the kernel with a limited set of interfaces, and thus severely restrict the potential scope of projects. Lawson et al [5] describe one project in which students modify a custom Linux kernel designed to run on the iPod. Hess et al [3] describe some projects taught during six terms, with a course assessment.…”

Linux has emerged as a widely-used platform for enabling hands-on kernel programming experience to learn about operating system concepts. However, developing pedagogicallyeffective programming projects in the context of a complex, production operating system can be a challenge. We present a structured series of five Linux kernel programming projects suitable for a one semester introductory operating systems course to address this issue. Each assignment introduces students to a core topic and major component of an operating system while implicitly teaching them about various aspects of a real-world operating system. Projects are of modest coding complexity, but require students to understand and leverage core components of the Linux operating system. The learning benefits for students from this approach include learning from real-world operating system code examples by expert kernel designers and gaining software engineering experience managing production code complexity. We have successfully used these structured Linux kernel projects to teach over a thousand students in the introductory operating systems course at Columbia University.

“…Others have used Linux, either on dedicated devices (e.g., iPodLinux [14]), or in virtualized environments [7,11,15], to provide an internal, concrete perspective. Compared to those approaches, Pintos provides a similar level of realism in that students can see the results of their work on concrete or virtualized hardware, but does not require that students understand the often arcane and ill-documented interfaces of the Linux kernel, which were not designed from an educational perspective.…”

Pintos is an instructional operating system, complete with documentation and ready-made, modular projects that introduce students to the principles of multi-programming, scheduling, virtual memory, and filesystems. By allowing students to run their work product on actual hardware, while simultaneously benefiting from debugging and dynamic analysis tools provided in simulated and emulated environments, Pintos increases student engagement. Unlike tailored versions of commercial or open source OS such as Linux, Pintos is designed from the ground up from an educational perspective. It has been used by multiple institutions for a number of years and is available for wider use.
