Why do we need to Virtualize Machines
First let's start with the reasons why to virtualize a machine. The main reason to virtualize a machine is the ability to run multiple operating systems without impacting the host operating system. Virutal Machines(VMs) offer advantages of manageability and security, as well as the flexibility of running a separate operating system and non-native applications, making them ideal for software developers and testers. For example, a VM is isolated or "sandboxed" from the host system and other VMs, meaning that the software inside a VM can't escape or tamper with the computer itself. This produces an ideal environment for testing other operating systems including beta releases, accessing virus-infected data, creating operating system backups, and running software or applications on operating systems they weren't originally intended for.
