Deploy graphics devices by using Discrete Device Assignment
Starting with Windows Server 2016, you can use Discrete Device Assignment (DDA) to pass an entire PCIe device into a virtual machine (VM). Doing so allows high performance access to devices like NVMe storage or graphics cards from within a VM while being able to apply the device's native drivers. For more information on devices that work and ...
Plan for deploying devices by using Discrete Device Assignment
To help ensure the hardware is capable of Discrete Device Assignment, you can run the machine profile script on a Hyper-V enabled host. The script tests if your server is correctly set up and what devices are capable of Discrete Device Assignment. Device requirements. Not every PCIe device can be used with Discrete Device Assignment.

Summary: Learn how to attach a device from your Hyper-V host to your VM by using a new feature of Windows Server 2016. Today we have a guest blogger, Rudolf Vesely, who has blogged here on previous occasions. ... One feature that drew my attention is a new feature in Hyper-V called discrete device assignment. It can be very simply described as ...
Discrete Device Assignment -- Description and background
With Windows Server 2016, we're introducing a new feature, called Discrete Device Assignment, in Hyper-V. Users can now take some of the PCI Express devices in their systems and pass them through directly to a guest VM. This is actually much of the same technology that we've used for SR-IOV networking in the past. And because of that, instead ...
How to deploy graphics devices using Hyper-V DDA
There are three main steps in performing a Discrete Device Assignment of a GPU: Preparing the VM, dismounting the Peripheral Component Interconnect Express, or PCIe, device from the host partition and making the device assignment within the VM. Admins must perform all three of these steps within PowerShell.
Setting up Discrete Device Assignment with a GPU
Below I describe the steps to get DDA working. There's also a rough video out on my Vimeo channel: Discrete Device Assignment with a GPU in Windows 2016 TPv4. Setting up Discrete Device Assignment with a GPU Preparing a Hyper-V host with a GPU for Discrete Device Assignment. First of all, you need a Windows Server 2016 Host running Hyper-V.
PDF Introduction to Windows Server 2016 Hyper-V Discrete Device Assignment
Discrete Device Assignment (DDA, also known as PCI Passthrough) is a performance enhancement in Microsoft Windows Server 2016 and Hyper-V. It allows a specific physical PCIe device installed on the host system to be directly and exclusively controlled by a guest virtual machine (VM). In this paper we describe the steps of how to configure an ...
Introduction to Windows Server 2016 Hyper-V Discrete Device Assignment
Discrete Device Assignment is a performance enhancement that allows a specific physical PCI device to be directly controlled by a guest VM running on the Hyper-V instance. Specifically, this new feature aims to deliver a certain type of PCI device class, such as Graphics Processing Units (GPU) or Non-Volatile Memory express (NVMe) devices, to a ...
Which GPU Assignment Method Should You Use for Hyper-V ...
2 GPU Assignment Methods. As mentioned earlier, Hyper-V provides two different options for assigning GPUs to virtual machines. One option is to use RemoteFX. The other option is to use a discrete device assignment. Unfortunately, neither option is suitable for every situation.

First published on TECHNET on Nov 24, 2015. In my previous three posts, I outlined a new feature in Windows Server 2016 TP4 called Discrete Device Assignment. This post talks about support for Linux guest VMs, and it's more of a description of my personal journey rather than a straight feature description. If it were just a description, I ...
A 1st look at Discrete Device Assignment in Hyper-V
Discrete Device Assignment (DDA) is the ability to take suitable PCI Express devices in a server and pass them through directly to a virtual machine. This sounds a lot like SR-IOV that we got in Windows 2012 It might also make you think of virtual Fibre Channel in a VM where you get access to the FC HBA on the host. The concept is similar as in ...
Issues to watch out for when configuring Discrete Device Assignment
If you try to change this on a VM with discrete device assignment enabled you'll also find that this isn't allowed. Cannot perform the operation for 'W2K12R2' as the specified memory settings are not compatible for device assignment. The startup memory size and minimum memory size must be equal when Dynamic Memory is enabled and devices ...
Discrete Device Assignment -- Description and background
Here's Device Manager from that VM, rearranged with "View by Connection" simply because it proves that I'm talking about a VM. In a future post, I'll talk about how to figure out whether your machine and your devices support all this. Read the next post in this series: Discrete Device Assignment -- Machines and devices
Discrete Device Assignment questions
But I have a few questions to the Nvidia doc. Q1: The documentation for 3.
