Introduction to Hypervisors

Hypervisors are key in virtualization technology, sitting between hardware and virtual machines (VMs). Knowing what a hypervisor is is vital for improving IT setups. They manage resources well and keep different operating systems separate on one machine.

What is a Hypervisor?

A hypervisor is software that lets many operating systems share one machine. It divides physical resources among VMs, ensuring they work well together. This tech boosts efficiency and makes the most of available resources.

Types of Hypervisors

Hypervisors are divided into two types: Type-1 and Type-2. Knowing these types helps us see how they work and where they fit best.

• Type-1 Hypervisors: These run directly on hardware. They offer top performance and are best for serious use. Examples are VMware ESXi and Microsoft Hyper-V.
• Type-2 Hypervisors: These run on an existing operating system. They’re easier to set up but might not perform as well. Examples include Oracle VirtualBox and VMware Workstation.

Understanding hypervisors and their types lets us look into options like Proxmox and VMware ESXi.
