CPU Virtualization

This lecture delves into the concept of CPU virtualization, exploring the core principles of systems such as abstraction, layering, and naming. The instructor discusses the definition of a virtual machine, the importance of matching attributes for virtualization, and the distinction between simulation and virtualization. The lecture also covers the Popek and Goldberg theorem of 1974, which establishes the conditions for constructing a virtual machine monitor. The instructor shares insights on the theoretical background of computer systems, the challenges of sensitive instructions, and the implementation of a virtual machine monitor. Additionally, the lecture touches on the evolution of virtualization technologies, the significance of hardware support for virtualization, and the practical applications of virtual machines in cloud computing.
