VirtualBox is an open-source hypervisor software; it allows you to create and run guest operating systems (“virtual machines”) such as Linux and Windows on top of the existing operating system (host). VirtualBox may be installed on host operating systems, including Linux, Windows, Solaris, OS X, and OpenSolaris.
VirtualBox is released under GPL v2 and Oracle VM VirtualBox extension pack is released under PUEL (Personal Use and Evaluation License).
You can install VirtualBox either using precompiled binaries or source code. This tutorial focused on installing VirtualBox using precompiled binaries (.deb).
Starting from the version 2.0, VirtualBox supports 32 and 64bit host and guest operating systems (To run 64bit guests, make sure your processor supports hardware virtualization and, the host operating system must be 64bit as well).
Kickstart a terminal to begin.
To add a VirtualBox repository, edit /etc/apt/sources.list file.
sudo nano /etc/apt/sources.list
Add the following line to above file.

sudo apt-get install dkms
Start VirtualBox (Dash >> Search >> Oracle VM VirtualBox).
On your first start, VirtualBox may prompt you to accept the license agreement.
Why are you waiting for? just go and create virtual machines. The following screenshot shows Fedora 24 running on VirtualBox.
