Thank you very much!

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

I also used instructions from @msupport

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.

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

@Tristis-Oris thanks a lot, but is says: The transfer you requested has been deleted. sorry for troubles

[Tristis Oris]

@timemaster5 omg. i suppose it removed by legal reasons. i can upload somewhere else, but have no idea.

@Tristis-Oris sharing my google drive link via chat... should be easy to upload it there

Let me update the procedure with my experience:

1. install XCP-NG 8.3
2. download XenServer Driver Nvidia 16.9 (latest supported by y M60)
3. unzip driver and copy host driver (NVIDIA-vGPU-xenserver-8-535.230.02.x86_64.iso) I used winscp to copy the driver to the tmp directory.
4. download XenServer iso file (https://www.xenserver.com/downloads | XenServer8_2024-12-09.iso)
5. copy the file (vgpu-7.4.16-1.xs8.x86_64.rpm) in the packages directory
6. yum localinstall vgpu-7.4.16-1.xs8.x86_64.rpm
7. yum localinstall NVIDIA-vGPU-xenserver-8-535.230.02.x86_64.rpm
8. reboot
9. install guest driver on the VM client (539.19_grid_win10_win11_server2019_server2022_dch_64bit_international.exe)

I preferred to use yum localinstall to be able to remove or update packages faster.

I have a question regarding vGPU, why i have profiles where i can have up to 4 heads? I don't have any option to add more than one display and i don't even understand how can i use them.
Thanks for the procedure, i'm a total newbie with vGPu.

Check the compatibility

You must configure the license for the client on the license server:

On the windows 11 client in the Nvidia control panel you have to specify the license server:

Check the authorization on the file:
