nVidia Tesla P4 for vgpu and Plex encoding

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
-
@splastunov
Thanks a lot.
This also works with the Nvidia M10 and Nvidia A16 graphics card.
Driver Version: NVIDIA-vGPU-CitrixHypervisor-8.2-550.54.10.x86_64 (Version 17.0) -
@msupport can you detail a bit what you did? thanks!
-
- Install XCP-NG Version 8.2.1 (8.3 did not work)
- Install all update yum update
- reboot
- Download NVIDIA vGPU drivers for XenServer 8.2 from NVIDIA site. Version NVIDIA-vGPU-CitrixHypervisor-8.2-550.54.10.x86_64 (Version 17.0)
- Unzip and install rpm from Host-Drivers
- reboot again
- Download free CitrixHypervisor-8.2.0-install-cd.iso from Citrix site
- Open CitrixHypervisor-8.2.0-install-cd.iso with 7-zip, then unzip vgpu binary file from Packages->vgpu....rpm->vgpu....cpio->.->usr->lib64->xen->bin
9.Upload vgpu to XCP-ng host to /usr/lib64/xen/bin and made it executable chmod +x /usr/lib64/xen/bin/vgpu - Deployed VM with vGPU and it started without any problems
- Copy License File from Nvidia License Portal (*.tok) to C:\program files\Nvidia Corperation\vGPU Licensing\ClientConfigToken
- Install Windows Nvidia Driver on Windows 10 VM (need connection to api.dis.licensing.nvidia.com Port TCP 443, use Nvidia Control Panel to set the hostname and port for Licensing the Nvidia Card)
Works fine for me
If you want to install the NVidia driver on XCP-NG 8.3. Manipulate /etc/xensource-inventory (line PRODUCT_VERSION from 8.3.0 to 8.2.0) during the installation. Then xe-install-supplental-pack NVIDIA-vGPU-CitrixHypervisor-8.2-550.54.16.x86_64.iso.
After installation, change PRODUCT_VERSION back to 8.3.0
The driver now also works in version XCP-NG 8.3
Do not forget to copy the vgpu file to /usr/lib64/xen/bin/vgpu. (change the chmod to 755)
Nvidia vGPU M10 | A16 on XCP-NG 8.3 Beta2 only work without XCP-NG updates. After the update, the error message "An emulator required to run this VM failed to start" appears. It must be due to one of the 76 updates that can be installed. I am trying to find out which update is causing this problem.

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

Okay so the only binary you need to get from Citrix is
vgpu
, right? -
Out of curiosity what are you using this for? what are these VM's doing?
-
@olivierlambert
yes, download and extract. Don't forget the permission.Download free CitrixHypervisor-8.2.0-install-cd.iso from Citrix site
Open CitrixHypervisor-8.2.0-install-cd.iso with 7-zip, then unzip vgpu binary file from Packages->vgpu....rpm->vgpu....cpio->.->usr->lib64->xen->bin
Upload vgpu to XCP-ng host to /usr/lib64/xen/bin and made it executable chmod +x /usr/lib64/xen/bin/vgpu

I use these Windows 10 clients with UDS Enterprise VDI System. From October 2025, it will be forbidden to run Office on the terminal server. That's why we switched to virtual desktops.https://learn.microsoft.com/de-de/deployoffice/endofsupport/windows-server-support

@splastunov Do the AMD GPU's not require a license?

Nope. These work easy out of the box. Installed the GPU on one of our servers yesterday.
-
@austinw no licenses, but a lot of troubles.....

Curious, what troubles?
-
@mohammadm
I'm talking now about vGPU not passthrough- old drivers
- no way to monitor GPU load
- Sometimes the GPU on Dom0 stops responding and the only thing that can be done to solve this problem is to reboot the entire server with all the virtual machines on it.
and etc.... do not remember all troubles I had with it
