What is Hyper-V Virtualization? Learn about Microsoft's virtualization technology

Hyper-V virtualization is a virtualization technology developed by Microsoft, allowing the creation and management of multiple virtual machines on a single Windows server. Hyper-V helps businesses optimize hardware resources, increase flexibility, ensure security, and serves as an important platform for building private cloud and hybrid cloud in modern IT environments. Let's join Vcloudia to explore the contents presented below in more detail.

What is Hyper-V Virtualization?

Hyper-V virtualization is a virtualization technology developed by Microsoft that allows you to create and manage virtual machines (VMs) right on a Windows-running computer or server. Hyper-V operates as a hypervisor that can divide hardware resources (CPU, RAM, disk, etc.) so that multiple operating systems run independently on a single physical machine together.

In modern infrastructure models, Hyper-V is often used to build a private cloud within the enterprise. From this platform, the system can expand or connect to a Virtual Private Cloud on cloud platforms such as Azure.

Outstanding features of Hyper-V:

- Pre-installed on Windows 10/11 Pro, Enterprise, and Windows Server versions.

- Allows creating, running, and managing multiple virtual machines on the same device.

- Supports multiple operating systems such as Windows, Linux, FreeBSD...

- Increases flexibility and security when deploying IT infrastructure.

- Compatible with management tools such as Hyper-V Manager, PowerShell, and Azure.

What components does the structure of Hyper-V consist of?

Hyper-V virtualization is built according to a layered architecture, helping the system operate stably, securely, and easily scale. Basically, the structure of Hyper-V consists of three main components along with some auxiliary components that support managing and operating virtual machines.

Core components

- Physical server and management partition (Root Partition): This is the physical server with the Windows operating system installed and Hyper-V enabled. The Root Partition has direct access to hardware such as CPU, RAM, disk, and network. This partition is responsible for managing the system, creating, and coordinating resources for virtual machines.

- Hypervisor: The hypervisor is the core layer of Hyper-V, sitting directly on the physical hardware. This component does not run applications but only performs the task of separating and allocating resources like CPU and memory to partitions, ensuring that virtual machines operate independently and without conflict.

- Virtual machines and child partitions (Child Partitions): Each virtual machine is created in a separate child partition. In these partitions, users can install an operating system such as Windows or Linux. Child partitions do not access hardware directly but use resources through virtual devices provided by Hyper-V.

Auxiliary components

- Hyper-V management tools: Hyper-V provides multiple tools for administering virtual machines such as Hyper-V Manager, PowerShell, and Windows Admin Center. These tools allow creating, configuring, monitoring, and managing virtual machines on the familiar interface of Windows.

- Virtual hard disks (VHD/VHDX): Each virtual machine uses one or more virtual hard disks to store the operating system and data. Hyper-V prioritizes the VHDX format due to its capability to support large capacities, high stability, and better performance compared to traditional VHD.

- Virtual network (Virtual Switch): The Virtual Switch is the component that helps connect virtual machines to each other and to external networks. Hyper-V allows creating various types of virtual switches to control traffic, separate networks, and enhance security for the virtualization system.

Operating mechanism of Hyper-V

Hyper-V operates through the hypervisor to control the use of the physical server's hardware resources. When the system boots up, the Root Partition is created first and plays the role of coordinating the entire virtualization environment.

The virtual machines in the child partitions send resource requests to the hypervisor. The hypervisor will use a scheduling mechanism (scheduler) to allocate CPU, memory, and other resources reasonably, helping multiple virtual machines run simultaneously while still ensuring performance and stability.

Thanks to this model, Hyper-V ensures isolation among virtual machines, limits mutual influence, and maintains performance even when the system operates with multiple workloads at the same time.

Outstanding features of Hyper-V virtualization

- Live Migration: Transferring virtual machines between physical servers without disrupting services, ideal for maintenance or load balancing.

- Dynamic Memory: Automatically adjusting RAM for virtual machines according to demand, optimizing resource usage.

- Hyper-V Replica: Synchronizing virtual machines to another location for quick recovery during incidents (Disaster Recovery).

- Clustering & Load Balancing: Enhancing High Availability for critical applications.

- Nested Virtualization: Running Hyper-V inside a virtual machine, useful for development and testing environments.

- Enhanced graphics support (RemoteFX): Providing a better graphics and audio experience, supporting applications that require graphical resources.

- Strong security: Integrating features like Secure Boot and Shielded VMs to protect virtual machines and data.

- Comprehensive management: Deeply integrated with tools like PowerShell and Windows Admin Center for automation and centralized management.

- Support for multiple operating systems: Allowing Windows, Linux, and other operating systems to run on the same physical hardware.

Pros and cons of Hyper-V virtualization

According to Faddom, Hyper-V currently accounts for about 10–12% of the global virtualization market share and is an increasingly popular choice for businesses using Windows due to its economical nature. Although highly rated thanks to its reasonable cost, good integration capability with the Microsoft ecosystem, and high stability, this platform still has certain limitations when compared to other virtualization solutions

Comparison between Hyper-V and VMware virtualization

In the field of server virtualization, Hyper-V and VMware are the two most popular and widely used platforms today. Each solution has its own strengths, suitable for different infrastructure needs and scales.

Guide on how to enable and disable Hyper-V on Windows 11

How to enable Hyper-V on Windows 10 and Windows 11

To use Hyper-V on Windows 10 and Windows 11, your computer needs to support virtualization technology (Intel VT-x or AMD-V) and have Virtualization Technology enabled in the BIOS/UEFI. After meeting the requirements, you can enable Hyper-V directly in Windows via Windows Features without the need to install additional external software.

- Step 1: Open Control Panel, select Programs, then click on Turn Windows features on or off.

- Step 2: In the Windows features list, find and check Hyper-V, while ensuring that the two components Hyper-V Platform and Hyper-V Management Tools are also fully selected.

- Step 3: Click OK to confirm, wait for Windows to install the necessary components, and then restart the machine to complete the process of enabling Hyper-V.

How to disable Hyper-V on Windows 10 and Windows 11

While using Hyper-V on Windows 10 or Hyper-V on Windows 11, there are situations where you need to disable Hyper-V to avoid conflicts with other virtualization software such as VMware Workstation, VirtualBox, or Android emulators. Disabling Hyper-V virtualization can be done directly in Windows through Windows Features without needing advanced commands.

- Step 1: Open Control Panel, select Programs, then click Turn Windows features on or off.

- Step 2: In the Windows features list, uncheck Hyper-V. To ensure that Hyper-V on Windows 11 or Windows 10 is completely disabled, you should additionally uncheck:
