Hyper-V is a virtualisation technology developed by Microsoft which enables the efficient sharing of host compute resources between multiple virtual guest machines.

A native hypervisor, Hyper-V allows multiple virtual machine guests to run simultaneously providing access to host resources and virtual resources (such as networks, disks and other virtual machines).

Hyper-V was first available with Windows Server 2008 and is now available both as part of Windows Server and Client operating systems and as a no-cost stand alone product.
