What Is Hyper-V and How Does It Work?
Hyper-V is a product of Microsoft. It is a native hypervisor available as an optional add-on to Windows Server. Hyper-V first became available in the year 2008 with Windows Server 2008.
Today, Hyper-V is also available with the Enterprise editions of Windows 8, Windows 8.1, Windows 10, and Windows 11, as well as the x64-bit Pro.
Hyper-V is now also available as a standalone server. The Hyper-V server is available for free from Microsoft, but it comes with a restricted set of functionalities.
It is essential to point out that Hyper-V is a type-1 hypervisor (or what is also known as bare-metal). Hyper-V directly runs atop the computer hardware and underneath the guest and host virtual machines. It has proven capabilities that can benefit companies operating in any sector. Moreover, Microsoft, a reputable software company with a dominating market presence, supports Hyper-V.
A Hyper-V-supported infrastructure has the Hyper-V installed on the host operating system. Accordingly, this becomes the parent VM. The guest VMs or virtual machines may operate on different operating systems. These are known as child VMs. The guest and host virtual machines draw from this infrastructure’s server resources. Yet, the parent VM is designed in such a way that it can allocate computing resources to the guest VMs.
