What is a Virtual Disk Image?

A Virtual Disk Image is copy of an operating system (called Guest Operating System ) which can run in your machine (called Host Operating System). Usually, the Guest OS is customized with custom programs installed on top of it. Virtualization software enables one to test another OS without the need for physically installing it in the disk or it enables one to execute certain programs which are available only for the guest OSes.
