@olivierlambert Yeah I guess that is true ... Nvidia Titan and Threadriper pro are at least workstation. It is just interesting that consumer GPU's are working on other platforms and not xen/XCP-NG.

RE: GPU passthrough, Windows 11 guest, "Working properly" becomes "Code 43"
hello this is what I am seeing as well. When I use this gpu on bare metal it works. Within any windows VM it jsut crashes with nvlddmkm.sys. I have run DDU and the newest drivers and it is a fresh install of windows with all of the patches.
I have changed the vga option on and off. After putting a dongle for fake screen in the devic it seems a little better but the RDP is choppy and slow and keeps dropping off. There are posts for proxmox where you have to set it to use the second display not the default windows one, but I cant even be in RDP long enough to make that happen

RE: GPU passthrough, Windows 11 guest, "Working properly" becomes "Code 43"
@branpurn Hello, while I do not have an answer I am seeing similar behavior. I have tested this on two different vms. One VM was windows server 2019 and one was windows 10 LTSC 21h2. I can setup the VM and install all updates, when I install the Nvidia drivers and reboot I can no longer see the console in XOA and cannot RDP to the VM. I have tested the cli version of pcie passthrough removing it from the system first then passing it to the VM and then also using the dropdown from within XOA for passthrough and neither are working for me. I am on a beta version of XCP-ng and I am trying to pass a Nvidia titan GPU to the VM. I have also installed parsec and its vga driver and this did not help. As soon as i Remove the GOU i can see it in the console and RDP to it again.

I have attempted this on an Intel v4 Xeon platform and had some of the same issues and could not get it working.

RE: GPU passthrough, Windows 11 guest, "Working properly" becomes "Code 43"
@planedrop That has also been my experience as well in the past. I have attempted this again recently because last year Nvidia changed the drivers in a way that code 43 should no longer be an issue with most GTX gpus that people would be trying to pass into a VM. There are many videos of this just working in Proxmox and VMware with those driver changes. I do not get the code 43 error when installing the device drivers in the VM, just BSOD as seen above and reboots. If there are special steps needed to make this work on XCP-NG it would be great if we could get that documented, the other thing is that both of these systems are running on AMD and there might be bios changes we need to make?. https://nvidia.custhelp.com/app/answers/detail/a_id/5173/~/geforce-gpu-passthrough-for-windows-virtual-machine-(beta)

@olivierlambert Understood, I only used this option from under advanced and did not manually install the xcp-ng tools.

RE: GPU passthrough, Windows 11 guest, "Working properly" becomes "Code 43"
@branpurn Under advanced in XOA there is an option to install drivers with windows update. Do we need those drivers for the GPU to work probably not, but 99% of the time you should have the xen drivers installed to make the system be happy and work better.
Items within the device manager may not be installed correctly without xen drivers.

RE: GPU passthrough, Windows 11 guest, "Working properly" becomes "Code 43"
would it matter if we are using the Cirtix "windows install drivers" from advanced vs the XCPng drivers for the VM? I am using the windows update option.
