nVidia Tesla P4 for vgpu and Plex encoding
-
Haha, it finally works!!!
The problem was with the template I used to deploy the VM.
I first deployed a VM from the default Windows 2019 template and it was not possible to install the GPU drivers.After that I tried deploying the VM from the "other installation media" template and now I can install any drivers.
To make it work with different benchmarks, I installed the Quadro RTX 5000 driver (from consumer site).
The result is on the screen. About 60 average FPS.
I think it is limited with driver on host.
As you can see FurMark detected GPU correctly T4-Q8.
Result from eth classic miner.
Miner detected GPU as T4 too.
No licenses are required : )

@splastunov Hmmm, not sure that will work for long for a P4 or T4 without an NVIDIA license. At some point, it will likely throttle down to a maximum of 3 FPS after the grace period expires.
Then again, you might get lucky.

Weird, something in the Windows template is make it fail? That's interesting information

Hi everyone,
I'm interested too in the use of Nvidia GRID in XCP-ng because we have a cluster with 3 XCP-ng servers and now a new one with a GPU Nvidia A100. It would be great if I could use it in a new XCP-ng pool, because it's an excellent tool and we already have the knowledge.
Our plan is to virtualize the A100 80 GB GPU so we can use it in various virtual machines, with "slices" of 10/20 GB, for compute tasks (AI, Deep learning, etc.).
So I have two questions:- The trick copying this vgpu executable can be dangerous when updating the XCP-ng server? Maybe overwriten, deleted or something.
- Do you have plan of supporting nvidia vGPU soon? We still can use Qemu over Ubuntu or other Linux with this drivers and everything works ok but XCP-ng is more professional than qemu IMHO.
You are doing a great great job at Vates. Keep going!

@Dani I made a post yesterday about Nvidia MiG support. vGPU support on XCP-ng is tricky because of the proprietary code bit that makes vGPU work can't be freely distributed. On the other hand, MiG (which is supported by many Ampere cards like to A100) doesn't requiring licensing like vGPU and seemingly just creates PCI addresses for the card which could, in theory, be passed through to VMs.
CC: @olivierlambert since we briefly talked about this yesterday in my thread.

@wyatt-made thanks a lot. What a qick response!!
I'll check your post.
My plan is to install xcp in the A100 server Next week and test It. I will post the results in the forum and maybe will help @olivierlambert and the rest of the community.Dani

I will be interested to understand how MiG works and if we are far or not to get a solution for it
-
@splastunov is it still not asking for license ?
-
@hani it began asking for license after one day but without throttling.
I have switched to AMD GPUs

@splastunov Thanks thats expected
