Full Overview of Hyper-V Dynamic Memory Best Practices. Hyper-V Dynamic Memory was first introduced in Windows Server 2008 R2 with SP1. Prior to its release, a Hyper-V virtual machine (VM) would start and run with the full amount of RAM assigned to it, which resulted in memory overuse and affected overall VM performance. Is it feasible, or even possible, to boot Windows Server Hyper-V Core from an SD card? You can doesn't mean you should. SD cards are supported by Hyper-V but only within OEM deployment scenario. Besides the obvious part that server has a lot of 'server' features, AD, deduplication, less reboots, perhaps more stable, are there anything that will make it run much faster? I am considering installing a home lab, and want Hyper-V as the hypervisor. I don't really need all the features of Windows server 2019. Had a VM running on Windows Server 2019 Standard. The VM is a Windows Server 2016 instance. It was using the default Hyper-V Network adapter. It has worked for a few years. We de-commissioned that server and wanted to move the VM to a new server. Since this is a dev instance I exported the VM to a share, and on the new hypervisor (Windows.
The Hyper-V Amigos ride again! In this episode (19) we discuss some testing we are doing to create high performant backup targets with Storage Spaces in Windows Server 2019. We’re experimenting with stand-alone Mirror Accelerated Parity with SSDs in the performance tier and HDDs in the capacity tier on a backup target. We compare backs via the Veeam data mover to this repository directly as well as via an SMB 3 file share. We look at throughput, latency and CPU consumption.
One of the questions we have is whether an offload card like SolarFlare would benefit backups as these offload not just RDMA capable workloads. The aim is to find how much we can throw at a single 2U backup repository that must combine both speed and capacity. We discuss the reasons why we are doing so. For me, it is because rack units come at a premium price in various locations. This means that spending money to come up with repository building blocks that offer performance and capacity in fewer rack units ensure we spend the money where it benefits us. If the number of rack units (likely) and power (less likely) are less of a concern the economics are different.
When trying to Enabling Physical GPUs in Hyper-V, the option is not there in the GUI. In Windows 2016 there is an option as in the below screenshot:
In Windows Server 2019, here is the screenshot and there is no option to enable it:
So, Here is how to enable it in Windows server 2019. You can also use RemoteFX vGPU feature on Windows Server 2019. Although the config UI of RemoteFX vGPU has been removed from Hyper-V Manager of Windows Server 2019, you can configure RemoteFX vGPU by using Powershell on Windows Server 2019.
Check your Host GPU – You need RemoteFX Compatible GPU Card and you need to install the Remote Desktop Virtualization Host role in Windows Server Manager.
To install the Remote Desktop Virtualization Host role, open Server Manager, and select the Add Roles and Features option from the Manage menu. This will cause Windows to launch the Add Roles and Features Wizard. Click Next to skip the wizard’s Before You Begin screen. You will now be taken to the Installation Type screen. Select the Role-Based or Feature-Based Installation option and click Next. You will now be prompted to choose the server on which you wish to install the role. Choose the Select a Server from the Server Pool option. Make sure that the correct server is selected, and click Next. You should now see the Select Server Roles screen. Select the Remote Desktop Services role, and click Next. Click Next again to bypass the Features screen, and once again to bypass the Remote Desktop Services introduction.
The next screen that you will see asks you to select the role services that you wish to install. Select the Remote Desktop Virtualization Host checkbox, as shown below. If prompted to install the Media Foundation and the Remote Server Administration Tools, be sure to click the Add Features button.
Click Next, followed by Install, and the required role services will be installed onto the server. When the process completes, click Close. You will need to reboot the server in order to finish the installation.
Now open powershell as Administrator.
Run the following commands:
Look for the following:
CompatibleForVirtualization: True
Enabled: True
Here is the screenshot for the Nvidia card I have. Make a note of the name of the card as well.
You can also use the name of the card directly or with a wildcard as below:
Next, Enable/Disable Host GPU for RemoteFX vGPU. To Enable, run this:
Next, stop the VM on hyper V. Then, Add RemoteFX vGPU to your VM:
Example: Add-VMRemoteFx3dVideoAdapter -VMName [vm_name]
Now, open the VM Settings in Hyper V so you can configure RemoteFX vGPU. You should see this:
Hyper-v Server 2019 Licensing
5) Start VM.
