Server Virtualization is the process of dividing a physical server into several virtual servers, called virtual private servers. Each virtual private server can run independently.

Types of Server Virtualization
1. Hypervisor
In the Server Virtualization, Hypervisor plays an important role. It is a layer between the operating system (OS) and hardware. There are two types of hypervisors.

Type 1 hypervisor ( also known as bare metal or native hypervisors)
Type 2 hypervisor ( also known as hosted or Embedded hypervisors)
The hypervisor is mainly used to perform various tasks such as allocate physical hardware resources (CPU, RAM, etc.) to several smaller independent virtual machines, called "guest" on the host machine.
