An Introduction to Virtualization. What is virtualization? Virtualization uses software that simulates hardware functionality "CPU, MEMORY, HDD" to create a Virtual Machine (VM). OS virtualization is the use of software "ESXi" to allow a piece of hardware "Physical Server" to run multiple operating system images at the same time. A hypervisor and the hardware let you split one physical system into separate VMs. The virtualization Layer is an additional abstraction layer between network and storage hardware, computing, and the application running on it.
Hypervisors have been split into two classes:
- Type I
Bare-metal hypervisors "ESXi" that run guest virtual machines directly on a system’s hardware.
- Type II
Hosted hypervisors "WorkStation" that abstract guest operating systems from the host operating system.
