https://www.sciencedirect.com/topics/computer-science/hypervisorsType 2 hypervisors, also known as hosted hypervisors, run on top of another general-purpose operating system, typically on a desktop or laptop computer. They are not directly installed on bare metal like Type 1 hypervisors.
Type 2 hypervisors provide a layer of abstraction between the guest operating system and the host operating system, allowing multiple operating systems to run concurrently on a single physical machine. They are commonly used for virtualization on personal computers or laptops for development, testing, or running legacy software.
In contrast, Type 1 hypervisors, also known as bare-metal or native hypervisors, run directly on the host machine's hardware without the need for an underlying host operating system. They provide better performance, stability, and security, which is why they are commonly used in production environments.
Regarding performance, Type 2 hypervisors introduce an additional layer of abstraction between the guest operating system and the hardware, which can result in some performance overhead. On the other hand, Type 1 hypervisors can provide better performance because they have direct access to the physical hardware.
Finally, neither Type 1 nor Type 2 hypervisors directly allow access to CPU virtualization features. Instead, they provide a virtualization layer that abstracts the underlying hardware and presents virtualized hardware to the guest operating systems. However, Type 1 hypervisors are generally better equipped to take advantage of CPU virtualization features like hardware-assisted virtualization.
