- Nested_virtualization abstract "Virtualization, in computing, refers to the act of creating a virtual (rather than actual) version of something, including but not limited to a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. A hypervisor is a software layer that creates the virtualization by abstracting away the underlying physical infrastructure and presenting virtual resources to the system. The term virtual machine (VM) typically refers to an encapsulated entity which includes the operating system, the applications running inside it as well as meta data that define it. It is treated as a “guest” which runs on top of a physical server which serves as the “host”. Virtualization is often considered the key enabling technology in delivering Infrastructure As A Service (IaaS)Nested virtualization refers to the act of creating an additional layer of abstraction and encapsulation in a pre-existing virtualized environment. In nested virtualization, the differences in hypervisors, networking and storage in different clouds are abstracted, thus enabling existing virtual machines to be run on third-party hypervisors and on other clouds without any modifications to the original virtual machines or their networking. The term nested hypervisor refers to a software layer that runs on top of other virtual environments such as public IaaS clouds and enables unmodified guest VMs to run in these non-native environments. Further, it creates a higher level of encapsulation by treating multiple VMs along with their networking and storage configurations as a single entity, for standard operations such as snapshots and clones. Infrastructure as a Service (IaaS) clouds utilize virtulization technology to deliver cloud computing and each IaaS cloud differs in its implementation. The differences span from virtualization technology and hypervisors, through storage and network configuration, to the cloud management APIs. These differences make migration of a VM (or a set of VMs) from a private cloud into a public cloud, or between different public clouds, complicated or impractical for many use-cases. Nested virtualization is the technology that enables complete abstraction of underlying cloud infrastructure from the application virtual machines. This allows deployment of existing VMs into the cloud without any modifications, mobility between the clouds and easy duplication of the entire deployment.".
