GPU support and Nvidia Grid vGPU

@olivierlambert
I have found the solution. I will test the whole thing again tomorrow with a clean installation with rc1.

Oh great! Keep us posted!!

@msupport Please write up all the steps involved, as this would be very useful documentation for anyone else wanting to accomplish this. Many have delayed switching to XCP-ng because of not being able to make use of NVIDIA GPUs.

It works on 8.2 already even if it's not official at all

Installation instructions XCP-NG (RC1) Nvidia M10 | A16 GPU

install XCP-NG 8.3 RC1
download XenServer Driver Nvidia 17.1 (NVIDIA-GRID-XenServer-8-550.54.16-550.54.15-551.78)
unzip driver and copy host driver (NVIDIA-vGPU-xenserver-8-550.54.16.x86_64.iso) I used winscp to copy the driver to the tmp directory.
download XenServer iso file (https://www.xenserver.com/downloads | XenServer8_2024-06-03.iso)
copy the file (vgpu-7.4.13-1.xs8.x86_64.rpm) in the packages directory ! Do not use CitrixHypervisor-8.2.0-install-cd file vgpu-7.4.8-1.x86_64
unpack file vgpu-7.4.13-1.xs8.x86_64
copy the file \usr\lib64\xen\bin\vgpu (size 129KB) to \usr\lib64\xen\bin\ on your XCP-NG host (chmod 755)
(putty) /tmp/ xe-install-supplemental-pack NVIDIA-vGPU-xenserver-8-550.54.16.x86_64.iso
reboot
install guest driver on the VM client (551.78_grid_win10_win11_server2022_dch_64bit_international.exe)
token file from Nvidia (C:\Program Files\Nvidia Corporation\vGPU Licensing\ClientConfigToken*.tok)

Nvidia drivers 17.2 and 17.3 do not work yet (Guest driver crashes)
I will stay tuned and inform you about new findings

Have fun

Thank you very much!

@msupport Many thanks for your write-up! Have you experienced any issues communicating with the NVIDIA license server?

i have followed the documentation however for some reason the VMs wont power on with a vGPU profile attached. We are testing with NVidia M10 GPUs. I'm using xcp-ng 8.3 and NVidia host driver 17.1, also tried 17.2 and 17.3

This is the error

i also performed a clean install of 8.2, same power on issue when a vGPU profile is attached.

@Tristis-Oris

https://we.tl/t-VozEeV8TFB

May I ask for a re-up? For some reason, I don't see version 17 in my Nvidia Licensing Portal The latest is 16
