Virtualization classifications

Virtualization classifications

1. Hypervisor
2. Host based

Hypervisors:

• also called bare metal.
• A hypervisor is the primary component of virtualization that enables basic computer system partitioning (CPU,Memory and I/O).
• hypervisor is an architecture installs the virtualization layer directly on a clean x86 based system.
• It has a direct access to the hardware resources, rather than going through an OS.
• Examples : Oracle VM Server for SPARC, the Citrix XenServer, KVM, VMware ESX/ESXi, and Microsoft Hyper-V hypervisor.

         Benefits:

• More efficient
• Delivers greater scalability
• Robustness
• Performance

Hostbased:

•  Host operating system based  virtualization also called host based virtualization.
• Installs and runs the virtualization layer as an application on top of an OS and supports the broadest range of hardware configurations.
• BHyVe, VMware Workstation and VirtualBox are examples.
