A virtual machine (VM) is a software-based computer that exists within another computer’s operating system, often used for the purposes of testing, backing up data, or running SaaS applications. To grasp how VMs work, it’s important to first understand how computer software and hardware are typically integrated by an operating system. The operating system uses a page table to keep track of which pages are in physical memory and which are on the hard disk. When a program attempts to access a page that is not in physical memory, the operating system generates a page fault. The page fault interrupts the program and transfers control to the operating system.
