VirtualBox is a general-purpose full virtualizer for hardware. Targeted at server, desktop, and embedded use, it is now the only professional-quality virtualization solution. It is also Open Source Software. The powerful virtualization product for enterprise as well as home use.
VirtualBox provides are useful for several scenarios: Running multiple operating systems simultaneously. VirtualBox allows you to run more than one operating system at a time.
This way, you can run software written for one operating system on another (for example, Windows software on Linux or a Mac) without having to reboot to use it.
Since you can conﬁgure what kinds of “virtual” hardware should be presented to each such operating system, you can install an old operating system such as DOS or OS/2 even if your real computer’s hardware is no longer supported by that operating system.
Software vendors can use virtual machines to ship entire software conﬁgurations. For example, installing a complete mail server solution on a real machine can be a tedious task.
With VirtualBox, such a complex setup (then often called an “appliance”) can be packed into a virtual machine. Installing and running a mail server becomes as easy as importing such an appliance into VirtualBox.
