Virtualization
Virtualization represents running software, usually multiple operating systems, concurrently and in isolation from other programs on a single system, called host. The software entity that controls virtualization is called hypervisor. The virtual machines executing on the host under the control of the hypervisor are known as guests or guest operating systems.
Virtualization Platforms
- RedHat Virtualization
- VMware vSphere
- Microsof Hyper-V
Hypervisor
The software entity that controls virtualization is referred to as hypervisor. The hypervisor manages the hardware resources of the host system and makes them available to the guest operating systems.
Hypervisors: KVM, Xen, VMware ESX.
Host Operating System
The host operating system (or the host OS) is the operating system of the physical computer on which the hypervisor is installed.
Guest Operating System
The guest operating system (or the guest OS) is the operating system that is running inside the virtual machine.
