  In computing, a virtual machine (VM) is the virtualization or emulation of a computer system. Virtual machines are based on computer architectures and provide the functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination of the two. Virtual machines differ and are organized by their function, shown here: [...] A 'virtual machine' was originally defined by Popek and Goldberg as "an efficient, isolated duplicate of a real computer machine." Current use includes virtual machines that have no direct correspondence to any real hardware. The physical, "real-world" hardware running the VM is generally referred to as the 'host', and the virtual machine emulated on that machine is generally referred to as the 'guest'. A host can emulate several guests, each of which can emulate different operating systems and hardware platforms. [...] A special case of process VMs are systems that abstract over the communication mechanisms of a (potentially heterogeneous) computer cluster. Such a VM does not consist of a single process, but one process per physical machine in the cluster. They are designed to ease the task of programming concurrent applications by letting the programmer focus on algorithms rather than the communication mechanisms provided by the interconnect and the OS. They do not hide the fact that communication takes place, and as such do not attempt to present the cluster as a single machine.[citation needed]

• What is a virtual machine (VM)?

  The operating system of a VM, commonly known as the guest operating system, can be identical to or different from the host OS and the OSs of other VMs on the host. A single computer can therefore host several virtual machines running different OSs and applications, without them affecting each other. Although the VM still depends on the host’s hardware, these resources are virtualized and distributed among the VMs and can be reallocated if necessary. This allows different environments to operate simultaneously to accommodate fluctuating workloads. From the user’s perspective, the VM works the same way as a physical machine. In most cases, users who connect to a VM do not know that they are using a virtual environment. [...] A process virtual machine allows a single process to run as an application on a host machine. The VMs therefore provide a programming environment independent of the platform by hiding the information of the underlying hardware or operating system. An example of a process virtual machine is the Java virtual machine, which allows any operating system to run Java applications as if they were native to that system. A system virtual machine is fully virtualized to replace a physical machine. A system platform supports sharing a computer's hardware among multiple virtual machines, each running its copy of the operating system. This virtualization process relies on a hypervisor, which can run on raw (unconfigured) hardware, such as VMware ESXi, or on top of an operating system. [...] # What is a Virtual Machine? As organizations seek to maximize resource efficiency while adapting to ever-changing technologies and customer expectations, the use of virtual machines (VMs) is growing exponentially. Understanding how virtual machines work is therefore important for IT professionals, as they become a central part of growth and IT strategies. machine_virtuelle.jpg ## VMs in Detail A virtual machine (VM) is a computing resource that uses software instead of a physical computer to run programs and deploy applications. One or more 'Guest' VMs are running on a 'Host' physical machine.
