Virtualization War: VirtualBox Vs VMware

This VirtualBox Vs VMware tutorial includes a comprehensive comparison between the two most popular tools of Virtualization called VirtualBox and VMware:

The term Virtualization is not alien to most people nowadays. Virtualization is a technology that allows the user to create multiple virtual environments using the physical resources of a machine.

It is a technology that creates a simulated environment similar to that of a physical machine which means the virtual environment created is similar to that of a physical machine and has an Operating system, Server, and Storage device.

Understanding Virtualization

Let us try to understand the concept of virtualization from the following image.


As we can see in the above image, the hypervisor software connects directly with the physical hardware, allowing you to split a single system into multiple Virtual Machines (VMs) and distribute the machine resources appropriately.

To explain in simple words, Virtualization

  1. One hardware or physical resource can create many virtual resources. Or
  2. One virtual resource can be created from one or more hardware.

There are a lot of virtualization tools available in the market. This article will cover, in detail, the comparison between the two most popular tools of Virtualization called VirtualBox and VMware.

Both Virtualbox and VMware work on the concept of a Virtual Machine (VM). VM is a replica of a physical computer and also has an Operating system loaded on it which is called Guest OS.

Let us start by understanding the basics of both VirtualBox and VMware and then we will delve into a detailed comparison of the two.

What Is VirtualBox

VirtualBox can be explained as a virtualization software that enables the user to run multiple Operating systems simultaneously on the same machine. For example, a user can use different versions of Windows (Win7, Win 10) or Linux, or any other Operating System on one single machine and also run them at the same time.

VirtualBox is a free virtualization software, which is ready to be used by enterprises and is developed for users of Windows OS. This has been designed by Oracle Corporation. It has been constantly upgraded to meet the performance standards that the industry demands. It is one of the most popular software for virtualization.

The following are benefits of VirtualBox:

  • Cost-effectiveness and increased celerity: Virtualbox provides the user with the ability to make use of virtualization using their home computers. It helps the user to create a depiction of an Operating System, thereby reducing hardware cost and surging productivity and effectiveness.
  • Easy installation and set-up: The installation of a Virtual box is a cakewalk for Techies or people with little or no technological background. It simply includes reading a manual from Oracle and following the instructions. The entire process of installation on a computer with RAM of 2 GB does not take more than 5 minutes.
  • User-friendly interface: The interface of the Virtualbox is simple and user-friendly. The main menu primarily consists of Machine, File, and Help as options and a user can use “Machine” as an option to create the desired Operating System. The next step requires the user to make a choice regarding the type of Operating System and a unique name for the OS.
  • Resourceful: The software has been upgraded to the latest version, where the user is able to scale the display. Here the size of the window can be minimized, yet the user can view everything. VirtualBox also allows the user the feature to cap or limit the CPU and IO time of the virtual machine. This ensures that the resources of the hardware or user’s own machine do not get drained.
  • Personalization: There are various Operating Systems like Linux. Mac and Solaris are supported by VirtualBox. The user can choose to create multiple platforms or assemble them on one server, which can be used for the purpose of testing and development.

What Is VMware

VMware is one of the world-renowned service providers for Virtualization. VM refers to Virtual Machines. VMware Server is a product that allows the user to compartmentalize a server into many virtual machines, thereby letting multiple operating systems and applications run successfully and simultaneously on one host machine.

Virtualization products from VMware have increasingly become an indispensable part of the IT infrastructure of all organizations- big or small.

VMware also provides a bundle of benefits. These are as follows:

  • Increased efficiency: The resources of a physical computer are not always put to optimum utilization. Some users do not prefer to run multiple applications on a single server OS as the damage to one application can have a ripple effect on other applications making the OS unsteady. If one was to solve this problem by running each application on its own server, a lot of wastage of resource of the physical machine will take place. The optimum solution for this issue is VMware. It allows each application to run in its own OS on one server of the physical machine.
  • Optimum Utilization of space in data centers: When more applications run on the same or fewer servers, the cost of managing space at data centers also considerably reduces.

Virtualization War: VirtualBox Or VMware

All this while we have been talking about Virtualization and we looked at how both VirtualBox and VMware allow the user to work on Virtual Machine.

So, are they all the same? Which one should we select to use? How are they different?

Before we answer this question and understand the differences between VMware vs VirtualBox, it is important to understand that despite the similarity of working on Virtual Machines, the way they work is very different. This is because of the software called Hypervisor, which is used to install and run Virtual Machines.

VMWare vs VirtualBox

Hypervisor is an important software as it provides the environment required to run Virtual Machines. They are responsible to create the much-required separation between the Operating system of the virtual machine and the hardware of the host machine. The host machine is capable of sharing its resources like memory, and a processor with many virtual machines.

The Hypervisor can be of two types:

  • Type 1 Hypervisor: This Hypervisor does not need any additional software for the process of installation and directly works on the hardware resources of the host machine. Example- VMware ESXi, vSphere.

Type 1 Hypervisor

Type 1 Hypervisor

  • Type 2 Hypervisor: This Hypervisor is also called a Hosted Hypervisor and is installed on the Operating System of the host machine. The installation process is as simple as that of any other software. Unlike Type 1 Hypervisors, Host Hypervisors do not directly access the hardware and resources of the physical machine.

Type 2 Hypervisor

Frequently Asked Questions

Below are some frequently asked questions about VirtualBox and VMware.

Q #1) Does VirtualBox slow down the user’s computer?

Answer: Much to our surprise, the answer to this question is Yes. When we use Virtual Box, it along with the guest OS consumes resources like CPU usage and memory of the host physical machine and it, in turn, slows down the performance of the physical machine. But the good news is that we can limit the usage of these resources by Virtual Box.

  • One of the solutions to this problem is to increase the minimum speed of the processor. This has shown considerably great results in dealing with the slow speed of the host machine.
  • The other option is to change the settings for the power plan which is selected. It is important to make sure that while running Virtual Box, the power plan chosen is high instead of the optimal power plan.

Q #2) Is Virtual Box legal?

Answer: VirtualBox is a popular software developed by Oracle and is widely used in the IT infrastructures of modern-day organizations. Virtual Box is certainly legal, but it comes with clearly run disclaimers.

These include:

  • A user needs to ensure to have a valid license for a Virtual box as a software. This is similar to how most other software is licensed. VirtualBox has been licensed under GPLv2.
  • A user also needs to procure a license to install and use a particular Operating system on the virtual machine. Most of these programs’ software has clearly laid guidelines to consider a physical machine and a virtual machine as separate despite being used on the same hardware.

Q #3) Is VMware faster than VirtualBox?

Answer: Some users have claimed that they find VMware to be faster compared to VirtualBox. Actually, both VirtualBox and VMware consume a lot of resources from the host machine. Therefore, the physical or hardware capabilities of the host machine are, to a great extent, a deciding factor when virtual machines are run.

Q #4) Which Virtual Machine is the best?

Answer: It is certainly not easy to conclusively say which machine is the best. Both VirtualBox and VMware have their share of advantages and disadvantages. Users can make a choice based on preferences, existing infrastructural setup, and application.

  • While VirtualBox offers cost benefits (it is available for free with an open-source license), it has also added various features like paravirtualization, which makes it a tough competitor for VMware Workstation. Virtual box is suitable for users who are not sure which OS they will be using, as its support is widely available on major OS like Windows, Linux, and Solaris.

Q #5) What is better than VirtualBox?

Answer: In terms of competition, VirtualBox has faced tough competition from VMware Player which is a free version. VMware Player has proven to provide users with a robust, secure, and far more stable environment for virtualization. VMware works on major OSs like Windows and Linux.


It is indeed a tough choice to make between VirtualBox vs VMware and what helps best to make this choice is usage and preference. If the virtual machine is not needed to fulfill the virtualization needs of an organizational setup, a Virtualbox is a choice to make. It is free, easy to install, and requires lesser resources.

VMware remains the first choice for organizations that have an existing VMware set up and can fund the cost of license and support and prefer a seamless performance.

VirtualBox and VMware both are promising solutions for virtualization. The choice is for the users to make based on the evaluation of the pros and cons of each of these options and taking into consideration the existing infrastructure and end-use.

We hope the article helps you make a viable choice.
