VirtualBox Installation

Introduction;

VirtualBox is a powerful software that allows users to run multiple operating systems on a single machine. It is widely used in computer fundamentals, enabling users to create virtual environments for software testing, running legacy applications or experimenting with different operating systems without the need for additional hardware. With its user friendly interface and versatile features, VirtualBox has gained popularity among both personal and professional users in the computing world.

What is VirtualBox?

VirtualBox is a freely available software program developed by Oracle Corporation that enables virtualization of the x86 computing architecture. Functioning as a hypervisor, it allows users to create virtual machines where they can run alternative operating systems. The “host” OS refers to the operating system on which VirtualBox itself runs.

The operating system running on the Virtual Machine is referred to as the “guest” OS. When you set up a virtual machine, you have control over the number of processor cores, amount of RAM and disk space allocated to it. During its operation, you can also choose to pause the VM if needed.

History of VirtualBox

The history of VirtualBox dates back to its development by Innotek GmbH. Initially, it was introduced as an open source software package on January 17, 2007. Later on, Sun Microsystems acquired the company and eventually, Oracle Corporation took over the production of VirtualBox after acquiring Sun on January 27, 2010.

Features of VirtualBox

VirtualBox offers a range of features that are worth mentioning. Some of the key features include;

1. Portability; VirtualBox is a cross platform Type 2 hypervisor that allows virtual machines created on one host to be executed on other hosts. The Open Virtualization Format (OVF) enables easy import and export of guest virtual machines based on specific needs.

2. Guest Addition; These are sets of tools installed within the guest operating system to enhance performance and provide seamless integration and communication with the host system.

3. VM Groups; VirtualBox provides functionality for organizing virtual machines individually or collectively into groups. This allows users to perform various operations such as starting, pausing, closing, resetting, shutting down, saving state, powering off individual or groups of virtual machines.

4. Hardware Support; VirtualBox supports various hardware capabilities including Guest SMP (Symmetric Multiprocessing), multiscreen resolution display support, built in iSCSI (Internet Small Computer System Interface) support for storage devices, USB device integration,

full ACPI (Advanced Configuration and Power Interface) support for power management,

and PXE (Preboot Execution Environment) network boot capability.

5. Snapshot ; VirtualBox allows users to save snapshots of the VM state, enabling them to easily revert back to a previous state of the virtual machine whenever needed.

How the VirtualBox Works?

Well, Oracle VirtualBox is designed to be both flexible and scalable. In simpler terms, it enables us to run multiple operating systems on top of it. Each operating system can be started, paused and stopped independently from one another.

VirtualBox utilizes a hypervisor that functions as a kernel service at Ring zero. The kernel includes vboxsrv, which acts as a device driver tool responsible for various tasks. These tasks include loading hypervisor modules for functionality, allocating physical memory to the virtual machine and saving/restoring the context of the guest system. Whenever an interruption occurs, we can switch to another operating system to handle VT x or AMD V activities.

The user manages OS scheduling during its execution. It operates as a single process on the host system and is scheduled by the host itself. Additionally, there are other device drivers present when the user permits access to resources such as disks, network controllers and other devices. Alongside kernel modules, there are other processes running on the host that assist in running the guest system. When a guest VM is booted from the VirtualBox GUI, the VBoxSVC process automatically starts running in the background.

Installation of VirtualBox in Windows

Installing VirtualBox on WindowsTo install VirtualBox on a Windows system, you can follow these steps;

Step 1; Start by opening your internet browser and navigating to the official VirtualBox website at https;//www.virtualbox.org/. This is where you will find the download link for the VirtualBox setup file.

Step 2; Locate and click on the “Downloads VirtualBox” button, which is displayed as a blue button on the webpage.

Step 3; Next, find and click on the link for Windows host. It should be located below the option labeled “VirtualBox 6.1.16 platform packages”.

Step 4; Once you have downloaded the VirtualBox file onto your system, open it by running the VirtualBox EXE files.

Step 5; On the Welcome window, click on the “Next” button.

Step 6; Choose a folder for installation and then proceed by clicking on the “Next” button.

Step 7; Now, select the features you want to install and then click on “Next”.

Step 8; Confirm your selection by clicking on “Yes” to install Oracle’s VirtualBox interfaces.

Step 9; When prompted, click on the “Install” button to begin installing VirtualBox in your system.

Step 10; Once all these processes are completed, click on the “Finish” button. This will close the installation tab and open VirtualBox. Now you can create a virtual machine to run any operating system on your computer.
