Background Information<\/h2><\/div>\n\n

A Virtual Machine (VM) is the virtualization\/emulation of a computer system. Virtual machines are based on computer architectures and provide marginal functionality of a physical computer. Virtual Machines also be considered a Guest Device, which is a virtual computer with their own CPU, Memory, Network Interface, and Storage all located on a Physical Machine known as a Host Device with the two being separated by a software called a Hypervisor. In some cases, the use of Virtual Machines may require the use of specialized hardware, software, or a combination of the two.<\/p>\n\n
