Hypervisors, also known as Virtual Machine Monitors, enable virtualisation. This distributes host system resources to guest environments.

 

Hypervisors are two types: 

• Native Hypervisor, also known as a Bare-metal Hypervisor,runs straight on the underlying host system guaranteeing direct access to the host hardware, thereby eliminating need for base OS.
• A hosted hypervisor uses the underlying host operating system with the current installed OS.
