VirtualBox ( Oracle VM VirtualBox ) is a virtualization software for x86 & AMD64 / Intel based system from Oracle. Virtualbox allows us to run multiple operating system as the same time . We can say VirtualBox is very powerful andcross-platform virtualization software.

In this Post we will discuss how to install Virtualbox in Ubuntu 14.04 / 14.10. Before starting installation let us discuss some ofvirtualization terminology.

• Host Operating System ( Host OS ) – It is an operating system of the physical machine on which virtualbox is installed or will be installed. Host OS for virtual box can be Windows, UNIX and Mac OS X.
• Guest operating system ( Guest OS ) – It is an operating system which is running inside the virtual machine.
• Virtual machine ( VM ) – This is the special environment that VirtualBox creates for our Guest OS while it is running. In other words, we can say that we run guest OS in a VM.
