VirtualBox was mainly built by Innotek GmbH under the supervision of Sun Microsystems; however Oracle Corporation bought it after some time. It supports the creation of virtual host machines and manages the guest servers in a great manner. It was first released in the year 2007 and since then it has been improvised to an advanced level. Its latest stable version has been released recently in 2018 to help both professional as well as private users. It is open source software that can be downloaded and used for free.
Virtualbox are increasingly becoming popular with most IT professionals all over the world. Virtualbox makes it possible to run other operation in one machine as a guest OS. With virtual box, one can have several operating systems using the resources of one computer. Virtualbox has proven to be very useful for people running tests on their local machine. Using a virtual box, one can study the behaviour of malware tools and viruses on a windows computer. In addition, one can use a virtual box for software testing since it can accommodate more than one operating system.
Virtualbox can be viewed as a prototype of the virtualization concept in cloud computing. In cloud computing, virtual servers which have shared resources are used for computing. There are numerous benefits of using Virtualbox for personal computing. To start with one can save snapshots that are essential for restore in case of a disaster. In addition, Virtualbox minimizes hardware costs and are flexible in resource allocation. With virtual box, one can run more than one Oss on the same physical machine.
VirtualBox can be used on every machine that works on Linux, OS X, Open BSD, Windows 10, Solaris and OpenSolaris host Operating Systems or their derivations. It is also capable of supporting a few selected host types on Apple iOS with limited features. Due to some issues it offers very low support for Mac OS. Though it is a complete software yet the developers have made customized packages that provide limited features for guest host systems. As a result these systems offer better quality of graphics, speed and performance.
For using Oracle VirtualBox software there are no charges applied. It is a free tool that you can use for personal, educational or commercial use. There are three versions of this software: GNU General Public License, Base package that can work with 1.1 USB port only and the Extension Pack version is compatible only with USB 3.0 support.
Oracle VirtualBox makes separate Virtual machines for every individual host. The configuration can be done in three ways: Software virtualization, hardware virtualization and device virtualization. Software based virtualization configures OS code though coding. The hardware assisted virtualization is available for Intel and AMD-V systems. The hard disks are considered in three formats: VDI, VMDK and VHD. After passing through each configuration, Virtual Host is set up properly.
It supports 64-bit systems. The clipboard is shared among users and the option of taking snapshots is available too. Connected systems can access shared folders for data sharing. Only Public APIs of Java, Python etc. are used for managing virtualization modes. It supports many Storage emulation features that include limited IO bandwidth, image encryption for protecting data theft and Microsoft VHD compatibility. It enables the use of SATA, PATA, SCSI, SAS, iSCSI and floppy disk controllers.
Many versions have been released since it was developed for the first time. Every version included many more features than the previous ones. The performance of this software keeps getting better and better due to the regular updates that are made by the developers.
