As we know that VirtualBox is a free cross-platform virtualization tool for x86 and Intel64/AMD64 hardware. Using VirtualBox, we can run multiple operating systems simultaneously and help users to setup their test environment on their desktop or laptops. It is generally used as desktop level and provides a graphical user interface for managing virtual machines.

Basic terminology used for VirtualBox

  • Host OS: It is the operating of your physical system on which VirtualBox is installed.
  • Guest OS: It is the operating system which is running inside the virtual machine.
  • VM (Virtual Machine): It is a virtual environment created by virtualbox for running the OS.
  • Guest Additions: These are special software designed to install inside the VM to improve guest OS performance.
