8.3 isn't even officially released I don't see any reason why it would break between beta 2 and RC1, but if you can confirm it, we could investigate. There's no rush to get out of 8.2, it's still an LTS

Have you took the drivers for XS8, which is equivalent from XCP-ng 8.3?

EspenU

@olivierlambert Would that mean that the vgpu binary should be taken from XS8 as well when using XCP-ng 8.3?
During testing I tried using that binary in XCP-ng 8.2, and it didn't work (VMs would no boot). I had to use the one from Citrix Hypervisor 8.2.

msupport

@olivierlambert
I have tested the Nvidia XenServer version 17.0.

olivierlambert

I don't know all the versions, but I can tell that:

XCP-ng 8.2 == XS 8.2
XCP-ng 8.3 == XS 8

So be sure to use the right/matching binary first

msupport

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

olivierlambert

Oh great! Keep us posted!!

tjkreidl

@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.

olivierlambert

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

@olivierlambert
Thanks for the hint, that helped me a lot

olivierlambert

Thank you very much!

tjkreidl

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

Nvidia licence server works perfectly so far

i can't find where to get this new nvidia driver. Tesla V100.

upd
looks the only way is license portal https://nvid.nvidia.com/. sad.

@Tristis-Oris
The driver version 17.1 worked for me, 17.2 and 17.3 crashed the Windows drivers
