The data is then sorted and compressed, optimizing the drive without compromising data integrity. Further improvements come in the form of a new VM configuration format.
Vmcx files make data reading and writing more efficient, and lessen the chance of corruptions. Though Windows Server introduces some major improvements, there are also smaller ones that are very interesting. Microsoft is working with GPU vendors to add support for specific GPUs, which could be useful for graphic intensive programs like rendering software and Photoshop. A Connected Standby power state is now available, even with the Hyper-V role installed. If a message appears, the screen will light up, notifying the user.
Naturally, some of these new features come with hardware requirements. This is especially true if you want to utilize new features such as shielded VM and discrete device assignment. First off, the general Hyper-V requirements. There are several ways to tell if you meet these requirements, but the easiest is through command prompt or PowerShell.
You can follow these steps:. As mentioned earlier, Shielded Virtual Machines have further requirements. The host needs the following:. In addition, VMs need to be Generation 2, and the guest operating system must be Windows Server , R2, or The feature with the most requirements is Discrete Device Management. Hosts need supported processors, chipsets and firmware table, as follows:. The availability of guest operating systems also varies slightly with Windows Server While Windows Server has the best virtual processor support, other systems still provide great functionality.
Guest OSs also vary in the support for Integration Services. In general, Windows 8. Other versions usually require an upgrade or install after the guest operating system is set up.
Hyper-V support for Linux is a little more complex. Microsoft provides both emulated and Hyper-V specific devices, but the performance and features of emulated devices is limited. LIS is integrated into the Linux kernel and is regularly updated, but this may not extend to users on older distributions. Thus, some users must download LIS manually.
That said, support for Linux in Windows Server is good, and builds on previous versions. Microsoft has LIS support for the following distributions:. There are issues with StaticIP injection across the board when Network Manager is configured for a synthetic network adapter.
In addition, VLAN trunking only works in 7. Debian also has some restrictions. There are live virtual machine backup problems here too, not working with ext2 filesystems. It also has issues with virtual fibre channels, where the machine may not be able to mount correctly if LUN 0 has not been populated.
Both RedHat and UEK may have to undergo a filesystem check if there are open file handles during backup and may fail silently if there is an iSCSI or pass-through disk attached. Similarly, live backup issues mirror that of Oracle VMs. Finally, Windows Server users must type memory parameters in multiples of MB or there will be Hot-Add failures and lack of a memory increase.
Ubuntu suffers from some of the limitations mentioned earlier. Microsoft also has some best practices for running Linux on Hyper-V.
Other than OS and feature support, Hyper-V varies in its scalability. While we have mentioned some of the virtual hardware increases in Gen 2 VMs, there are other factors to consider too. Here are the maximum numbers for each virtual machine component:.
You will not find any options related to Hyper-V in the console-based server configuration menu. You can create users, install updates, change computer names, manage network settings, enable remote management, shut down or restart the server, and exit to CMD. VMs can be created , deleted, started, stopped, renamed etc.
For this, you need another Windows machine with the Hyper-V role installed. Clustering is supported by Hyper-V Server The entire cluster configuration can be done with PowerShell. Hyper-V Server can also be used for educational and testing purposes or for companies that do not have high numbers of VMs that must be licensed. A paid license must be applied to Windows Server on a per-core basis except for the Essentials edition — but using this is not rational for Hyper-V.
You can select the Standard or Datacenter edition. The Windows Server Standard edition includes licenses for two Windows-based Hyper-V virtual machines and is suitable for smaller virtualized environments. Windows Server Datacenter Edition includes licenses for unlimited numbers of Hyper-V virtual machines running Windows, and accordingly is recommended for highly virtualized environments. Moreover, the Datacenter edition allows you to deploy shielded VMs and use Storage Spaces Direct, with storage replicas and a software-defined networking stack.
After choosing the deployment option you want to use in your Hyper-V environment, you should ensure that your Hyper-V system is securely protected and can be rapidly recovered in case of disaster. For this purpose, consider installing an efficient and affordable data protection solution which can back up, replicate, and recover your VMs onsite, offsite, and in the cloud.

VM licensing has always been a confusing topic for many users due to the multitude of implications and liabilities that it entails. Currently, Microsoft customers who want to build a highly functional Hyper-V environment can choose between two deployment options: the Hyper-V role on Windows Server and free Hyper-V Server.
Unfortunately, when choosing between the two options, customers rarely consider the implications that go along with each of them, especially in terms of licensing. This blog post compares the Hyper-V role on Windows Server and free Hyper-V Server and outlines the virtualization rights and licensing rules that each of these options provides.
In one of our previous blog posts, we described in detail how Hyper-V role and Hyper-V Server differ in terms of installation, user interface, VM management, clustering, use cases, and licensing. So, what is the main difference between the Hyper-V role and Hyper-V Server when it comes to licensing?
Starting from the release of Windows Server , Microsoft has changed its licensing model. As a result, processor-based licensing has been replaced by core-based licensing, and new storage features have been introduced. Windows Server licensing entails the following:. Hyper-V Server was released as a standalone product in and has been available free of charge ever since.
Hyper-V Server was specifically designed to provide virtualization services only. As appealing as free Hyper-V Server may seem at first glance no licensing fee, a lightweight tool, and virtualization capabilities , you should think before deploying this option.
It is recommended to first consider what free Hyper-V Server licensing includes:. When comparing free Hyper-V Server and the Hyper-V role on Windows Server , it becomes clear that the main distinction between them relates to licensing models, server capabilities, and VM management.
Thus, you can be sure that your VMs and Hyper-V host are properly licensed and your Windows Server can be serviced and supported by the Microsoft team.
On the other hand, if you decide to go with free Hyper-V Server , you will have to purchase additional OS licenses for all VMs running in your system.
Even though choosing and purchasing an OS license for every VM in the system might seem like a challenging and resource-intensive task, you still should not stop using Hyper-V Server. In fact, you can greatly benefit from use of free Hyper-V Server by installing open-source OSs, which are available for free and can be easily accessed and used by anyone.
They provide a high level of productivity and a rich feature-set, which makes open-source OSs a great alternative to using licensed Windows-based OSs. As you already know, free Hyper-V Server and the Hyper-V role on Windows Server are essentially the same hypervisor with similar sets of features and server capabilities.
However, while Windows Server provides a wide range of server roles, free Hyper-V Server serves only one purpose, which is server virtualization.
If you only need a server for purposes of virtualization and want to minimize costs associated with Hyper-V deployment, free Hyper-V Server is the best choice for you. However, if you need a server with an advanced set of server roles and capabilities, you are prepared to purchase an OS license, and want to enjoy the benefits of readily available technical support, then you should deploy Windows Server with the Hyper-V role enabled.
This way, you can avoid the pitfalls of using either Hyper-V Server or Windows Server and make the most use of these deployment options. Nevertheless, before starting to build your Hyper-V environment, you should pay attention to VM licensing and understand the licensing implications in full. After choosing the deployment option you want to use in your Hyper-V environment, you should ensure that your Hyper-V system is securely protected and can be rapidly recovered in case of disaster.
For this purpose, consider installing an efficient and affordable data protection solution which can back up, replicate, and recover your VMs onsite, offsite, and in the cloud.

I have question regard Windows Server Standard Hyper-V role licensing, because every person are have different word about it. What about Linux VMs? Are they limited too? Some general info - Each host needs to be licensed.
For each additional 1 or 2 VMs, all the physical cores in the server must be licensed again. Dave Patrick Ok Because one told that only 2 VMs max can be running in Hyper-V role even linux ones2nd told that linux VMs doesn't count.
