Best Virtualization System To Create VPS

Virtualization is a new solution in computer science and networking that will reduce the cost and increase efficiency. Virtualization is designed to create a layer between computer and software systems hardware. Although this design is done by considering the ratio of consumer resources.

Virtualization actually gives you the ability to consider a group of servers as a unique resource for computing resources to operating systems, as well as allowing you to run multiple operating systems on one server simultaneously. Now, with the knowledge of server virtualization in this article, we intend to examine the differences between several popular virtualizers.

What Is A Hypervisor?

The term hypervisor was first invented by IBM in 1956 for advanced software programs with RPQ capability on IBM 360/65 computers that shared computer RAM. A hypervisor is a model of hardware virtualization that allows you to run and use multiple guest operating systems at the same time on a single host system.

In this case, virtual operating systems installed, like any real operating system, will be able to use hardware resources in a system such as CPU or Hard and RAM. The hypervisor actually refers to meeting the hardware requirements of the guest operating system and managing the communication between them and the extent to which they benefit from the hardware resources.


The hypervisor is also called another (VMM), which stands for Virtual Machine Manager, and basically both refer to the same subject and do not differ. But in general, there are two types of hypervisors.

  1. The first type is provided to you as a platform and allows you to install a number of other virtual operating systems directly by installing it on server hardware. Examples of this type include VMware ESXi, Citrix, and XenServer. This type of hypervisor is also called Bare-Metal.
  2. The second type is installed on the host operating system and you can use it to install and run your guest OS.


What Is The Difference Between Hypervisor Type 1 and 2?

The difference between the first and the second type is that in the second case the hypervisor is highly dependent on the host OS, and if there will be problems with host OS, other guest operating systems, such as VMware Server, Windows Virtual PC, Microsoft Hyper-V, and VMware Workstation will face some issues.

Difference Between Virtualization Systems

Virtual servers are generally implemented with the help of a virtualization system, and in the configuration of these virtual servers, it is considered that the allocation of resources to the virtual server is such that it can operate independently and also prevent disruption for other operators. Familiar names for virtualization systems include KVM, OpenVZ, VMWare, and Xen

What Does Virtualization Do Exactly?

What a virtual maker does is to share resources and create separate, independent servers and machines. For example, when we install a virtual machine in a home computer, we can divide the resources of that computer, ie RAM, Processor, etc., into different parts (machines).
And each of these parts is an individual system with individual operating systems. We call these parts a Virtual Private Server (VPS).

They have their own factor, and each can manage their resources individually, without affecting the performance of the adjacent machine. When we do the same thing on a server, we will have a virtual server instead of a virtual machine. If we install a Windows OS on the server, we will call it a Windows VPS and if we install Linux OS, it will be called a Linux VPS.

What Is Overselling?

In fact, overselling means that more resources are sold to users than the server itself. For example, if the server has 100 GB of hard drive, there will be no limit on the service sales of one terabyte or more. Considering that no user will use all of their server resources, providers offer too many servers.

Overselling usually reduces the quality and performance of the virtual server. In virtualizers that use this, users can write a lot of input and output on the server on the disk, which can affect other users as well.

However, this often results in less costly service to the user, in which case you can use more resources without paying more. But that’s not the case for medium and large businesses.

Now let’s look at some of the famous virtualization systems.


A virtualization system that is open-source and is supported by Red-Hat. In this virtualizer, it is necessary for Linux to be part of the central core of the host operating system, but at the same time, there are conditions for setting up a virtual Windows server. Since resources are fully allocated to the client in KVM, we will not see overselling.

  • The disadvantage of KVM: higher cost compared to OpenVZ virtualizer.
  • The advantage of KVM: No overselling and compatibility with Linux and Windows.

This virtualizer is also an open-source virtualizer that is free and its installation environment is Linux. It also generally allows the virtual machine to be installed automatically and therefore does not require much technical information. But in OpenVZ virtual machine, it is not possible to provide a Windows operating system and only Linux should be used.

  • The disadvantage of OpenVZ: Limited to Linux operating system and reduced service quality due to over-selling.
  • The advantage of OpenVZ: Possibility of automatic installation of the operating system and reduction of service costs and cheapness due to pre-sale.

It is a type of BareMetal virtualizer and is commonly used on large, commercial servers. In VMware, more features can be obtained compared to other virtualizers. This virtualizer also has good support.

  • The disadvantage of VMware: High cost.
  • The advantage of VMware: No overselling and compatibility with all operating systems.

Xen is also a virtualizer of BareMetal and is from the Linux kernel.

  • The disadvantage of Xen: The higher price compared to Openvz and slower than KVM.

Xen virtualization


Hyper-V is one of the largest virtualization products in the world, which allows you to use virtual technology to deliver a load of your real environment virtually.

Hyper-v virtualization

Hyper-V allows you to present your hardware virtually so that you can have as many virtual machines on your physical system as your hardware supports. Every virtual machine is completely isolated and virtual, no different from a physical system.


Now, in the end, it is you who can answer to the question “Best Virtualization System To Create VPS” and to take advantage of your desired virtual machine according to the needs as well as the specified budget. If the price is important for you and wants a virtualization system that supports all operating systems, KVM will be the best option. If the price is not the case, then VMware will be the best.

If you just want to create Linux VPS, OpenVZ will be the best option. But finally, I think Vmware is the best because if you even have a little knowledge regarding virtualizing, VMware will meet your request because it has a user-friendly interface.
