In a particular VM, the guest OS is stored on a virtual hard drive—a big, multi-gigabyte file stored on your real hard drive.
The Workstation Pro package is ideal for professional users who desire a powerhouse virtual machine capable of simultaneously running applications on multiple guest operating systems.
Virtual machines have other advantages for operating system development and may include improved debugging access and faster reboots. Anything you install, or mess up, can be deleted with a few clicks of a mouse. For example, they are a great way to mess around with Linux—or a new Linux distribution—and see if it feels right for you.
Since the virtual machine is sandboxed from the rest of the system, the software inside the virtual machine cannot tamper with the host computer. Unlike virtual memory, a system virtual machine entitled the user to write privileged instructions in their code.
The software functions nearly identically regardless of the host platform, and even offers 3D virtualization, multi-screen resolutions, and laudable hardware support, among other features.
In the VM world, the operating system actually running on your computer is called the host and any operating systems running inside VMs are called guests. Virtual Machine Definition Virtual machines are software computers that provide the same functionality as physical computers. You can adjust these settings now via the System and Display menus.
Linux includes KVM, an integrated virtualization solution. A typical use would be to run a real-time operating system simultaneously with a preferred complex operating system, such as Linux or Windows. A special case of process VMs are systems that abstract over the communication mechanisms of a potentially heterogeneous computer cluster.
