Background Concepts

Virtualization

Before we delve into the details of our research paper, its essential that we provide some insight and background to the concepts and notions discussed by the authors.

Virtualization: In the contex of operating systems, virtualization is a method that allows a single OS to host one or more simulated environment instances (called virtual machines) that can run their own operating systems and applications with the illusion that they're running on the main hardware. [1]

Hypervisor: Tied to the concept of virtualization, a hypervisor (also called a virtual machine monitor) is a software that monitors the existence of the guest virtual machines and presents a simulation of the underlying hardware (CPU, MMU, I/O, drivers, etc.) to them to operate on.
