What Is VirtualBox?


VirtualBox is a free, open-source software program for creating and running virtual machines, making it an invaluable resource for IT administrators, software developers and others.

Linux virtualization provides you with the means to experiment and test multiple operating systems without needing to purchase new hardware, as well as boasts a large community that backs it.

It is free

VirtualBox is an easy and free virtualization program that enables you to run different operating systems on your PC without purchasing new hardware. It works with existing systems to simulate physical computers while offering advanced features not usually found on commercial software like VMware.

As part of its support for virtual machines, Virtual Box offers a range of networking modes. For instance, RDP and USB 2.0 and 3.0 devices as well as disk encryption make this an excellent solution for businesses that need to test software across various platforms or devices.

Once your virtual machine has been created, select your operating system of choice from the drop-down menu – for this tutorial we are using Linux but other OSes may work too! This tutorial uses Linux but any OS can be chosen instead. Next, specify where your virtual machine files should reside – by default they will be found in the directory with VirtualBox installed, but if necessary you can change this. Finally, allocate enough memory to your VM by specifying its size in megabytes (MB). Your virtual machine (VM) memory allocation options include either allocating a fixed amount or letting the program allocate memory dynamically as required. We advise allocating at least 16MB, which should provide enough room for most applications; to increase performance further and speed things up you should increase this to 32MB or beyond.

Once complete, select a host name and password to enable the virtual machine (VM). Enabling 3D acceleration may prove useful if installing an OS that requires it. Finally, click Start to launch your VM.

Your virtual machine is now ready to boot up and will present an OS-style interface that looks just like what is installed on its physical counterpart. Drag files between desktop PC and VM, or vice versa; additionally you can configure shared folders that will give access to specific folders on PC from within VM.

It is easy to use

VirtualBox, the free virtualization program, is easy to set up and use. It creates an accurate representation of an operating system so users can test software or develop programs without using up all their RAM resources. VirtualBox includes full ACPI support, multiple screen resolution options, iSCSI boot support, shared folder functionality and ACPI boot support among its features – making integration with host computers effortless! You can even add USB devices and security keys if desired – however ensuring sufficient RAM availability for successful operation of VM is crucial!

VirtualBox comes equipped with an easy setup wizard to assist with its installation process, but to get the best experience out of this software you will require enough storage space for any operating systems or programs you intend on installing in a VM – at minimum 10GB; more is always better!

Once the installation wizard starts, you will select a location to install VirtualBox software – although changing this may be beneficial depending on your situation. Next you will see a list of features it will install and can choose whether or not to select them; typically it is recommended that checkboxes near shortcut options and file associations be marked off as desired.

Once your installation is complete, you can launch your virtual machine (VM). It will run in a window on your desktop PC and capture mouse and keyboard input without affecting its host system. From here you can set its operating system and begin using it.

VirtualBox differs from VMWare by supporting an array of operating systems: all Windows distributions, most GNU / Linux distributions and even out-of-date operating systems such as OS/2 and DOS can all run on VirtualBox simultaneously. Furthermore, its hardware simulation capabilities make it possible to experiment with software and development environments, which makes testing and debugging applications much simpler. It’s also easy to monitor network traffic using third-party tools like Wireshark; all it requires is activating promiscuous mode on its network adapter!

It is easy to install

VirtualBox is an intuitive and effective program that lets you easily create virtual computers on Windows, Mac and Linux platforms. Its modular design makes it highly configurable; in addition it supports rare operating systems like Solaris OS/2 DOS QNX as well as AMD-V and Intel VT-x virtualization extensions present in host machine BIOSes.

VirtualBox can be easily installed from either Oracle’s website, or by accessing your distribution’s software repositories to get a prepackaged version. Choosing this route will likely provide faster, safer installation as well as optimal integration into your host OS for optimal performance.

When opening the installer, choose your language and location before clicking Next to start the installation process. When prompted to accept or decline license terms and conditions by pressing Y, press Y for acceptance to complete installation successfully and a message stating “Successfully Installed” will appear when completed.

Once VirtualBox installer is finished installing, you must set up your VM. Select an operating system you would like to install; either from CD-ROM or an image file will do. Next, choose either drive letter or browse location until finding file location before clicking Start to begin reading from disk or file.

Once finished, your virtual machine will be ready to boot up. Simply double-click its name in VirtualBox’s left menu on the main screen to launch it in a window on your host system; any keystrokes or mouse clicks that happen will only affect that virtual machine and not affect physical computers directly.

Your hard drive should have enough storage space available to you in order to accommodate virtual machine files, although if this is not sufficient you could use USB or SD cards as backup solutions. Your PC should also feature a powerful processor and plenty of RAM; additionally, 3D graphics technology should also be supported so as to ensure optimal performance.

It is easy to manage

VirtualBox can be easily managed through either its user-friendly GUI or command line interface, making it ideal for managing virtualization environments on a host system with multiple users simultaneously. Furthermore, its highly configurable nature enables it to support different hardware configurations and operating systems seamlessly – ideal for businesses seeking cost savings! With VirtualBox users can run and manage multiple virtual machines at the same time on one host system, using snapshots as error recovery measures when needed.

VirtualBox makes managing virtual machines (VMs) straightforward enough that even novice IT professionals can use it efficiently. Unlike VMware, which requires IT staff to learn proprietary software and hardware to operate it effectively, VirtualBox is modular and compatible with most host operating systems, so IT administrators can utilize one set of tools across platforms instead of purchasing dedicated hardware for each platform.

VirtualBox also provides features to make information exchange between host OS and virtual machine (VM) simple, such as sharing of the VM’s clipboard and drag-and-drop between them – particularly useful when moving large files such as applications or movies between computers. You can also share folders between them for efficient file exchange between computers.

Control of VM hardware is also key to managing its virtual machines (VMs), from network type and storage type, memory allocation (with 16MB being the minimum required), 3D acceleration for faster applications, etc.

Create a snapshot of the current state of a virtual machine (VM), which can help when you want to restore its state at an earlier point in time. To do this, shut down the VM before clicking the Snapshots button in the main menu to select and restore an individual snapshot – once restored, when next you load up that particular VM it will appear as it did when first captured in its snapshot form.
