It includes the VMware ESXi hypervisor, a type-1 (bare-metal) hypervisor approximating Hyper-V’s capabilities.

VMware vSphere is a virtualization platform, unlike Hyper-V, since it comprises a suite of virtualization products. Hyper-V features Secure Boot, helping protect virtual machines and their data from malware and other forms of unauthorized access. Known as Virtual Machine Connection, this tool features console access that allows you to see the events in the guest VM even when it is in an unbooted state.

Hyper-V has a remote connection tool that supports both Windows and Linux. Moving a VM somewhere else is easier since Hyper-V supports live migration, storage migration, and import/export. It also offers two backup methods, one using saved states and the other using Volume Shadow Copy Service or Volume Snapshot Service (VSS), as it is also known. Hyper-V can make backup copies of VMs and store them in other locations for later retrieval in case of disaster. Some essential features of Hyper-V include: Disaster recovery and backup Operating systems that do not support Enlightened I/O run on a slower emulation layer. Aside from Windows operating systems, Linux devices with kernels based on versions 3.4 and above and FreeBSD also support Enlightened I/O, allowing them to run faster on Hyper-V. Enlightened I/O bypasses any device emulation layer and allows direct access to VMBus. Hyper-V saves guest VMs to a virtual hard disk file and uses a high-level communication protocol called Enlightened I/O to access the physical hardware’s processing, storage, networking, and graphics components, among others.

This makes Hyper-V fast and scalable, as it directly accesses the hardware and does not need to load drivers and services during initialization. This design means that Hyper-V has less overhead for maintaining and managing devices and services that are not dependent on the hypervisor. Hyper-V utilizes a microkernelized hypervisor architecture where services and device drivers operate independently from the hardware layer. This work is performed behind the scenes, without any management needed on the parent and guest VMs. It uses a VMBus that runs from the parent VM’s Virtualization Service Provider to the guest VMs’ Virtualization Service Client. Although the parent VM and guest VMs essentially share the same resources on the server machine, the parent VM takes care of allocating the resources needed by the guest VMs. In a Hyper-V infrastructure, the host OS where Hyper-V is installed becomes a parent VM, and guest VMs installed with other operating systems are treated as child VMs. Hyper-V’s capabilities and the fact that it is designed and supported by Microsoft allows its use as a virtualization platform for any organization looking to expand its IT infrastructure.Īn Overview of the Hyper-V Infrastructure Hyper-V is a type-1, or bare-metal, hypervisor since it runs directly on the computer hardware and beneath the host and guest VMs. There is also a standalone Hyper-V Server with a limited function set that Microsoft makes available for free.

Hyper-V is also found in the 圆4-bit Pro and Enterprise editions of Windows 8, Windows 8.1, Windows 10, and Windows 11. Microsoft Hyper-V is a native hypervisor that has been an optional component in Windows Server products since Windows Server 2008. Hyper-V and VMware are two of the leading hypervisors in the market. A hypervisor that runs on top of the hardware and allows direct access to its components brings virtualization’s capabilities to the fore. Aside from lowering equipment costs and generating extensive cost savings, virtualization eases resource and IT management, improves business continuity with minimal downtime, and allows faster hardware and software provisioning. Virtualization allows a single piece of computer hardware to be shared among several virtual machines (VMs).
