What is Hardware Virtualization (Type I) characterized by?

Hardware virtualization, specifically Type I virtualization, is characterized by the ability to run a guest operating system directly on the physical hardware. This means that the virtualization layer, known as the hypervisor, operates directly on the host’s hardware without the need for an intermediary operating system.

In this model, the hypervisor manages the virtual machines, allowing them to operate concurrently while efficiently sharing the hardware resources among them. By allowing direct access to hardware, Type I hypervisors generally provide superior performance, scalability, and security compared to Type II hypervisors, which rely on a host operating system.

Options that suggest operating within a host operating system, using lightweight containers, or restricting access to applications do not accurately describe Type I virtualization. Instead, they refer to different virtualization or containerization approaches that do not leverage the direct interaction with the hardware.
