I have seen news of running Docker Dekstop on WSL2 on windows, where they are using a different mechanism other than Hyper-V to run docker containers on windows as they are run through the WSL 2 (ubuntu on windows
thing). I wonder whether as this develops we will be able to run Docker Desktop in parallel with Oracle VM Box without any problems.
With Microsoft Hyper-V, you can virtualize server operating systems in the data center or Windows phone environments on your desktop and most everything in between. It is also a great tool for developers that want a safe sandbox to test software.
When Microsoft Hyper-V debuted in 2008, virtualization was just beginning to become mainstream. Not many people knew what it was, and even fewer understood what they could do with it. It all seemed conceptually complicated, risky, and challenging to implement and maintain.
Each vendor offers additional products above and beyond the base product, notably System Center from Microsoft and vSphere from VMware. These two product suites differ quite radically in most metrics and are difficult to compare directly. Here are a few noteworthy items where Hyper-V is the clear winner:
For purposes of this article, we will focus on the general benefits of virtualization and highlight the particular features that are found in Windows Server with the Hyper-V role or with the free Hyper-V Server.
Hyper-V also provides a great deal of portability to your server-based applications. They can be easily moved to new hardware with little or no downtime. Workloads can be rebalanced if hardware becomes overloaded, or they can be quickly recovered on another system if hardware fails. The VHDX file format that Hyper-V uses to hold virtual machine data can be mounted by any current Windows operating system so you can recover data quickly and easily. Microsoft also allows customers to upload their own Azure-compliant VHDs and create Azure images for deployment.
With a physical infrastructure already in place, new operating system environments can be deployed from templates in a few minutes, drastically reducing the time necessary to provision and deploy a new Windows Server or Linux installation. DevOps tools such as PowerShell, Terraform, Ansible, and other tools can be used to interact with virtualized environments to further automate virtualized environments.
With the rapid provisioning and isolation features that are natural to Hyper-V, you can quickly design and deploy test and sandbox environments quickly. Disposing of them once testing has completed is even quicker. It makes testing patches, new applications, driver updates, and other tasks possible before rolling these into production.
All virtual machines running on a host or cluster can be viewed from a single pane using existing tools. For larger installations, management tools are available to monitor virtual machines across the entire datacenter. PowerShell and other tools enable mass simultaneous management of these systems.
Of all currently available virtualization platforms, Hyper-V Server is one of the few that has no price tag, regardless of the feature set. All features of Hyper-V are available in even the free edition, including failover clustering, multi-path I/O, Hyper-V Replication, and no artificial limits on CPU or memory utilization. While Hyper-V Server features are free, customers are responsible for the guest OS licenses running in the environment. Overall, it still provides a cost-effective solution for running specific workloads.
With the needs of a mobile workforce often exceeding the power of modern small devices, Hyper-V can provide a virtual desktop infrastructure (VDI) to supply high-powered desktop processing capabilities to low-powered laptops and handheld devices.
Client Hyper-V has one very important distinction among desktop hypervisors: it is a type 1 hypervisor whereas almost all others are type 2. A type 2 hypervisor is just an application that runs inside an operating system and is subjected to the same treatment as other applications, like Microsoft Outlook or a video game.
For your purposes, Client Hyper-V provides a much smoother performance profile than most competing desktop hypervisors. It also comes as a free, built-in component that requires no downloads, purchases, or separate update processes.
Microsoft has embraced the use of Client Hyper-V for other purposes, such as security, in the latest versions of Windows 10 & 11. In Windows 10 & 11, Microsoft leverages client-side virtualization technologies made possible by Hyper-V to instantiate Hypervisor-protected code integrity (HVCI). HVCI provides many security benefits, including:
As with any major technology group, virtualization has a long list of technical terms. Many of them are easy to understand when encountered in context, but some can be rather confusing, especially when not everyone uses them the same way. This list provides some of the most common terms and uses each of them in the same fashion as Microsoft documentation. In the interest of brevity, not all terms will be thoroughly explained here. Later material will explore all of these concepts in depth.
Hyper-V was first introduced with the 2008 series of Windows Server products. Since then, it has expanded its capabilities and added a significant number of features. In the current edition (Windows Server 2022), it is truly ready to power everything from a small business to a major enterprise.
As Microsoft continues to shift its focus to a Microsoft Azure cloud-driven ecosystem of products and solutions, it has detailed that Microsoft Hyper-V Server 2019 will be the last version of the free Hyper-V Server product in its current form. See the instructions on how to install Hyper-V on Windows Server 2019.
While Windows Server 2022 still includes the Hyper-V Role, there is no SKU for Hyper-V Server 2022. Instead, Microsoft is shifting to a new solution called Azure Stack HCI which is a cloud-licensed and delivered HCI solution that looks to be the roadmap for the Microsoft hypervisor technology we know as Hyper-V today.
Second-level address translation is a required feature for Client Hyper-V. It is not required for any server version of Hyper-V, but it is highly desirable. Memory operations, especially video, are greatly enhanced by this technology. This technology also has different names on different platforms. Intel refers to it as Rapid Virtualization Indexing (RVI) or Extended Page Tables (EPT). AMD calls theirs Nested Page Tables (NPT). As with DEP and hardware-assisted virtualization, SLAT has become very common.
These resources will allow you to explore the potential of Hyper-V. For a more comprehensive discussion of hardware usage in Hyper-V, refer to the following article: -v/hyper-vs-actual-hardware-requirements/.
Virtualizing and consolidating workloads leads to many advantages, including reduced energy demands, increased portability, rapid deployment, ability to easily provision lab environments, reduced management efforts, licensing savings, VDI capabilities, and many others.
Hyper-V capabilities are also built into Windows client operating systems, including Windows 10 and Windows 11. It allows running guest virtual machines on a Windows client machine. It is a great feature that is useful for development, browsing VMs, and many other use cases.
The Hyper-V platform continues to evolve and grow over time as Microsoft is further integrating Hyper-V capabilities into the SaaS Azure offerings, such as Azure Stack HCI and others. By making use of Hyper-V, organizations can modernize their enterprise data centers and successfully deploy hybrid cloud solutions.
Thank you for reaching out to the community forum.
Can you verify and review the current exclusion that you've added vs. the recommended exclusion that Microsoft shared? You may refer to this MS documentation and let us know if this helps. -GB/troubleshoot/windows-server/virtualization/antivirus-exclusions-for-hyper-v-hosts
Yes that is the document reference.
I've even tried disabling Sophos completely on the Hyper V Host Servers.
Appears to be something about the Hyper V Guests that Sophos product does not like.
We have Sophos working fine on other standalone and Amazon EC2 servers in our same domain/environment/Server SOE so we do not believe the issue is related to co-existence ith another application.
The goal of most organizations is to grow and expand over time. While meeting this goal, an organization also often finds it more difficult to properly and efficiently manage all aspects of its infrastructure. Modern businesses have long recognized the multiple benefits that virtualization can provide.
Hyper-V consolidates virtual servers onto a single physical computer, which allows you to significantly reduce the associated costs and management overhead. Moreover, Hyper-V enables better use of hardware by allocating computing resources to the VMs which need them most. Thus, you can build an easily scalable virtual environment which fully complies with your business needs and objectives.
Hyper-V is available as a server role in Windows Server and as a stand-alone product (Hyper-V Server). Moreover, Hyper-V Server is free to install. However, before you begin the process of installing Hyper-V, make sure that your system meets all of the following requirements:
Hyper-V is a built-in part of Windows Server 2008 and later. However, the Hyper-V role is not active by default, therefore you need to enable it manually. The process of installing the Hyper-V role is extremely easy and intuitive. There are three ways through which you can enable Hyper-V in your Windows system: Windows System Settings, PowerShell Command Line Interface (CLI), or Deployment Image Servicing and Management (DISM). The process of installing Hyper-V using Windows Control Panel, which is the most popular approach, will be demonstrated below.
