introduction to virtualization and how to get your first virtual machine running with the easy-to-use Oracle VirtualBox graphical user interface. Subsequent chapters will go into much more detail covering tools and features, but fortunately, it is not necessary to read the entire User Guide before you can use Oracle VirtualBox. You can find a summary of Oracle VirtualBox's capabilities in 1.3 Features Overview written for one OS on another, such as 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 OS, you
