What Is the Difference, and Does It Matter?

Hypervisors are important in the world of expertise. A hypervisor is a program that may be put in on a pc to run varied working methods reminiscent of Linux, Windows, macOS, and Solaris methods in a safe atmosphere. They are sometimes used to decrease operational prices, check methods, develop functions, and run varied servers.

There are two kinds of hypervisors: bare-metal or Type 1 hypervisor and hosted or Type 2 hypervisor, and each varieties have particular makes use of.

What Is a Type 1 Hypervisor?

Before we evaluate each kinds of hypervisors, let’s make sure you perceive what every kind means, what it does, and the way it works. Let’s begin with the Type 1 hypervisor:

Type 1 or bare-metal hypervisor is a virtualization software program used to create digital machines on high of the pc {hardware}. Direct {hardware} set up permits Type 1 hypervisors to be quick, environment friendly, and have higher safety when in comparison with a Type 2 hypervisor.

Type 1 hypervisors are usually put in on server {hardware} as they’ll make the most of the massive processor core counts that typical servers have. Type 1 hypervisors additionally enable reference to different Type 1 hypervisors, which is helpful for load balancing and excessive availability to work on a server.

The fashionable kinds of Type 1 hypervisors embrace VMware ESXi, Microsoft Hyper-V, and Citrix XenServer.

What Is a Type 2 Hypervisor?

A Type 2 or hosted hypervisor is a virtualization software program put in on high of the host working system that helps virtualization. Since it really works on high of an working system, Type 2 hypervisors aren’t as quick, environment friendly, or safe as Type 1 hypervisors. They are, nonetheless, adequate for varied Type 2 hypervisor functions, like utilizing a virtual machine to test a new operating system.

Some fashionable Type 2 hypervisors used right now embrace VirtualBox, VMware Workstation, and VMware Fusion. These hypervisors are generally put in on desktop PCs since they have already got an present working, which the Type 2 hypervisor can work on. Having a Type 2 hypervisor on a PC additionally makes it handy for individuals to make use of digital machines on their machine with none additional {hardware}.

Type 1 Hypervisor vs. Type 2 Hypervisors: What’s the Difference?

The largest distinction between each hypervisors is that Type 1 hypervisors are put in instantly on the pc {hardware}, whereas Type 2 hypervisors are put in on high of a bunch working system. This distinction dictates how every kind of hypervisor will work and what particular makes use of they’re higher fitted to.


Type 1

Type 2

Location Installed

Directly put in on pc {hardware}

Installed on high of the host OS

Virtualization Type

Hardware virtualization

OS virtualization


Guest OS and utility on the hypervisor

As an utility on OS


Takes benefit of high-core rely processors extra effectively, making it perfect for giant and high-scaling operations

Adequate for testing, growth, and tinkering


Direct {hardware} set up means every VM could be very protected from all host OS vulnerabilities

Provides sandboxed visitor OS making it adequately protected


Easy however some technical data required

Quick and simple

Suited Hardware

Type 1 hypervisors get their efficiency from excessive processor core counts; server-rated {hardware} is right

Type 2 hypervisors are used for smaller-scale operations and comfort; higher suited to PC {hardware}

Using the Right Type of Hypervisor Matters

Although each kinds of hypervisors have the identical duties of making digital machines, their variations make them higher fitted to totally different {hardware} and functions.

Using a Type 1 hypervisor on a desktop PC is not perfect since putting in it prevents you from utilizing a bunch OS to your each day private duties (although Microsoft’s Hyper-V considerably skirts round these points). In distinction, utilizing a Type 2 hypervisor on a devoted server considerably reduces efficiency, lowers safety, and prevents you from connecting to different Type 1 hypervisors, which are sometimes crucial for server features reminiscent of load balancing.

Type 1 hypervisors are higher fitted to devoted servers since they’ll make the most of all the Type 1 hypervisor functionalities to their fullest potential. On the different hand, Type 2 hypervisors are actually meant for use on private computer systems, as they’re sufficient for varied testing and growth functions whereas sustaining a bunch OS to your general-purpose functions.
