What is Virtual Machine?
A virtual machine may be defined as a software implementation of a hardware-like architecture executing predefined instructions in a manner like a physical central processing unit (CPU). These machines are used to create a cross-platform computing environment that loads and runs on computers without depending on their underlying CPUs and operating systems. Historically, virtual machines have been used for server virtualization. This enables IT systems to consolidate their computing resources and thus improve efficiency. Besides, virtual machines can perform specific tasks taken to be too risky to implement in a host environment, like accessing virus-infected data or testing operating systems. Isolated from the rest of the system, the software inside the virtual machine cannot tamper with the host computer.
