there is no need for a host operating system) in order to maximize hardware utilization, VM performance and compatibility. Professional server environments use hypervisors that run directly on hardware (e.g. run virtual machine inside another virtual machine inside a hypervisor ( our tutorial about installing VMware Player on Ubuntu Linux was actually done on a Windows computer!). Nested virtualizations are also possible e.g. There are many different hypervisors and software products (Microsoft Hyper-V, VMware Workstation, Oracle VirtualBox, Parallels Desktop are some of the big names in this area to name just a few – see full list here) and possibilities to install virtual machine on your existing physical computer. Virtual Machine is a virtualized hardware (software defined) running your favorite operating system (OS) on a similar or different physical computer hardware and/or operating system.Host Machine is a physical computer that runs Hypervisor and Virtual Machines.Hypervisor is a software application used to manage your virtual machine (VM) appliance and communicate between a host computer / operating system or directly with physical hardware.
