Hardware virtualization refers to the process in which a physical machine (host) uses hypervisor software to emulate one or more virtual machines (guests). These virtual machines function autonomously, each capable of executing distinct operating systems and applications as if they were separate physical entities.

Use Cases of Hardware Virtualization

How Hardware Virtualization Works

The hypervisor is the core component of hardware virtualization. It is software that connects with the physical hardware and allocates resources, including RAM, CPU, and storage, to each virtual machine. It ensures the VMs are isolated, which prevents them from affecting each other.

History of Hardware Virtualization

Hardware virtualization dates back to the 1960s when IBM designed a mainframe system to improve the efficiency of resource-intensive hardware.

It became widespread as personal computers and servers became more popular, leading to the emergence of players like VMware. Hardware virtualization has revolutionized IT by allowing for scalability, flexibility, and optimized resource usage.
