Operating System: Windows Server 2019 Standard I have enabled hyperthreading, intel virtualisation and vt-d, I know I can do passthrough as I tested with esxi 6.5 update 1 and I can passthrough graphic cards, sata drives, audio and usb connections. Feb 7th 2019 - An addition from tfl (thx for your comment Tom): 'I am using Hyper-V in Windows 10 and you do not need to do this. WIth this version of Hyper-V, you can simply use the New-Hard Disk feature in the Hyper-V MMC to create a new VHDX. As long as the device has a drive letter, you are good to go.
-->Hyper-V does not support a loopback storage configuration.This is a situation in which a Hyper-V system attempts to provide its own “remote” storage. As an example, you cannot have Hyper-V Server connect to a virtual machine running on a share that the same Hyper-V system is hosting. In this post I’m going to detail the steps I followed to setup a Windows Server 2016 Hyper-V Nano server image, and install it to the internal SD card of my home lab server, a HP ProLiant DL360 Gen8. Before getting started, you’re going to need a few things.: Windows Server 2016 ISO image; Windows 10 ADK. Requires applications that can leverage DAX (Hyper-V, SQL Server). Using persistent memory in a Hyper-V virtual machine. In a previous article “Configure NVDIMM-N on a DELL PowerEdge R740 with Windows Server 2019”, I showed you how to set up persistent memory for use on Windows Server 2019.

Starting with Windows Server 2016, you can use Discrete Device Assignment, or DDA, to pass an entire PCIe Device into a VM. This will allow high performance access to devices like NVMe storage or Graphics Cards from within a VM while being able to leverage the devices native drivers. Please visit the Plan for Deploying Devices using Discrete Device Assignment for more details on which devices work, what are the possible security implications, etc.
There are three steps to using a device with Discrete Device Assignment:
- Configure the VM for Discrete Device Assignment
- Dismount the Device from the Host Partition
- Assigning the Device to the Guest VM
All command can be executed on the Host on a Windows PowerShell console as an Administrator.
Configure the VM for DDA
Discrete Device Assignment imposes some restrictions to the VMs and the following step needs to be taken.
- Configure the “Automatic Stop Action” of a VM to TurnOff by executing
Some Additional VM preparation is required for Graphics Devices
Some hardware performs better if the VM in configured in a certain way. For details on whether or not you need the following configurations for your hardware, please reach out to the hardware vendor. Additional details can be found on Plan for Deploying Devices using Discrete Device Assignment and on this blog post.
- Enable Write-Combining on the CPU
- Configure the 32 bit MMIO space
- Configure greater than 32 bit MMIO space
Tip
The MMIO space values above are reasonable values to set for experimenting with a single GPU. If after starting the VM, the device is reporting an error relating to not enough resources, you'll likely need to modify these values. Consult Plan for Deploying Devices using Discrete Device Assignment to learn how to precisely calculate MMIO requirements.
Dismount the Device from the Host Partition
Optional - Install the Partitioning Driver
Discrete Device Assignment provide hardware venders the ability to provide a security mitigation driver with their devices. Note that this driver is not the same as the device driver that will be installed in the guest VM. It's up to the hardware vendor's discretion to provide this driver, however, if they do provide it, please install it prior to dismounting the device from the host partition. Please reach out to the hardware vendor for more information on if they have a mitigation driver
If no Partitioning driver is provided, during dismount you must use the -force option to bypass the security warning. Please read more about the security implications of doing this on Plan for Deploying Devices using Discrete Device Assignment.
Locating the Device's Location Path
The PCI Location path is required to dismount and mount the device from the Host. An example location path looks like the following: 'PCIROOT(20)#PCI(0300)#PCI(0000)#PCI(0800)#PCI(0000)'. More details on located the Location Path can be found here: Plan for Deploying Devices using Discrete Device Assignment.
Disable the Device
Using Device Manager or PowerShell, ensure the device is “disabled.”
Dismount the Device
Depending on if the vendor provided a mitigation driver, you'll either need to use the “-force” option or not.
- If a Mitigation Driver was installed
- If a Mitigation Driver was not installed
Assigning the Device to the Guest VM
The final step is to tell Hyper-V that a VM should have access to the device. In addition to the location path found above, you'll need to know the name of the vm.
What's Next
After a device is successfully mounted in a VM, you're now able to start that VM and interact with the device as you normally would if you were running on a bare metal system. This means that you're now able to install the Hardware Vendor's drivers in the VM and applications will be able to see that hardware present. You can verify this by opening device manager in the Guest VM and seeing that the hardware now shows up.
Removing a Device and Returning it to the Host
If you want to return he device back to its original state, you will need to stop the VM and issue the following:
You can then re-enable the device in device manager and the host operating system will be able to interact with the device again.

Example
Mounting a GPU to a VM
In this example we use PowerShell to configure a VM named “ddatest1” to take the first GPU available by the manufacturer NVIDIA and assign it into the VM.
Troubleshooting
If you've passed a GPU into a VM but Remote Desktop or an application isn't recognizing the GPU, check for the following common issues:
- Make sure you've installed the most recent version of the GPU vendor's supported driver and that the driver isn't reporting errors by checking the device state in Device Manager.
- Make sure your device has enough MMIO space allocated within the VM. To learn more, see MMIO Space.
- Make sure you're using a GPU that the vendor supports being used in this configuration. For example, some vendors prevent their consumer cards from working when passed through to a VM.
- Make sure the application being run supports running inside a VM, and that both the GPU and its associated drivers are supported by the application. Some applications have allow-lists of GPUs and environments.
- If you're using the Remote Desktop Session Host role or Windows Multipoint Services on the guest, you will need to make sure that a specific Group Policy entry is set to allow use of the default GPU. Using a Group Policy Object applied to the guest (or the Local Group Policy Editor on the guest), navigate to the following Group Policy item: Computer Configuration > Administrator Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Remote Session Environment > Use the hardware default graphics adapter for all Remote Desktop Services sessions. Set this value to Enabled, then reboot the VM once the policy has been applied.
When it comes to virtual machines, one of the most frequently asked questions is, what the heck are the differences and which should I choose? A tricky call for many. So, let’s get down to the nitty-gritty and answer that question once and for all.
Bring On the Beasts
Server 2019 Hyper-v Features
The biggest difference between the two is that VMware is a company and Hyper-V is a product. VMware’s product is called vSphere and is a platform designed for virtualization. Its two main parts are ESXi, which is the hypervisor, and vCenter Server which is a single pane of glass management server, a virtual machine that manages multiple hypervisors on multiple physical servers from a single point. Hyper-V is a Microsoft platform and hypervisor. With VMware, it could refer to either vSphere or ESXi. So Hyper-V is actually an arrow a role that you install on top of Windows server, and your Windows Server is ready for virtualization.
I’ve Got the Power
As for management, with Hyper-V, you manage your virtual machines using virtual machine manager (VMM) inside your system center, which is the standard way to manage Windows Server. So by installing VMM, you gain some new options with the server center, making it super useful for Windows Server administrators as they are familiar with the environment, and they can benefit from those extra perks that the increased functionality brings and they should be able to do it no time.
But I thought It Used to Be Different…
It’s true Hyper-V used to used to be designed only for Microsoft Server. Although you could run Linux within a virtual machine, it frequently just stopped working or you were getting some strange errors, and sometimes there were upgrades broke your virtual machine, so it was only suitable for Windows Virtual Machines. But this has changed greatly over the years, and actually starting from Windows Server 2012, Linux works with Hyper-V, and, in fact, Microsoft has become the largest contributor to Linux, which is strange, and they have added a lot of drivers for Hyper-V to make it run more smoothly. This makes Microsoft a great Linux contributor over the years, and Hyper-V is the reason they have done it.
Tell Me About the Features!
Interestingly, most of the features are the same but they often have different names so it can sometimes be confusing. For instance, there is a feature in VMware that allows you to move a running virtual machine from one physical host to another, which is called the vMotion, but with Hyper-V, they have exactly the same picture but is called Live Migration. This means you can be left scratching your head when choosing between the two, as the naming conventions make it difficult to compare the features – they are called differently, but they do the same things. So if you know the Microsoft name and what it is called in VMware, you can save yourself loads of time when comparing both products.
Try Walking in My Footprint
As has already been the case in this article, most of the bigger differences were historical ones. I was trying to find some differences and the truth is it seems to be that they were bigger differences in the old days. When I compare the current version of VMware, which is vSphere 6.7, to Hyper-V 2019, the differences are really tiny. VMware ESXi, the hypervisor, is actually an operating system on its own, it’s loosely based on Linux, but it’s written from scratch and it’s quite small. This used to be a big advantage of VMware, that the hypervisor itself could fit on an SD card or a flash drive. Typically when you worked with virtualisation, you had shared storage, you bought an enterprise storage array from Dell or HP and put your data there, and then you didn’t need RAID controllers and hard disks on your server – this meant you could save quite a bit of money. So you could buy shared storage and there you had diskless servers, and could install VMware on SD cards, which was on the servers. The diskless-server approach made a lot of sense because the disks were often the things that broke the most. It was simple, super cheap and worked perfectly. And you couldn’t do that with Hyper-V because Hyper-V needed you to install Windows Server, which was almost 40 gigabytes on its own, and then add the hyper-V role. The resulting footprints were large, and also with Hyper-V, you got frequent updates because of the codebase, so when Windows Server updated you also had to update Hyper-V.
And Have Things Changed?
Nowadays with Windows Server 2019 and Hyper-V 2019, they introduced something called Nano Server and it’s a very basic Windows Server installation. There is no GUI, and no remote desktop support. It is really tiny and less than one gigabyte. So the footprint has really has reduced, and also, VMware ESXi has become bigger because of added features. And although footprints are quite similar, there is still the difference that Windows Server cannot be installed on an SD card, but now the updates have a similar frequency, Hyper-V has nice Linux support, and now Hyper-V has become more reliable so I would say really the difference goes down to personal preference, plus support as well and also price of course.
As you can see from this first part, the development of the two platforms have taken them down different paths that have ironically caused many of their routes to converge. In the next part, I will take a look at some of the other factors that can help you understand those subtle differences in greater detail.
