here is what i'm currently running

i installed the nvidia host driver using rpm -iv "nvidia.rpm ive also tried other methods copying the .iso and installing the supplemental pack. One thing to mention is i grabbed the binaries from XenServer8_2024-10-03

rpm -ihv vgpu-7.4.8-1.x86_64.rpm

Here are my commands just to confirm I'm doing this right Do i still need to copy the binary to the location other have mentioned and make it executable?

and my install commands are just the binary.rpm and the nvidia host driver correct? I was basically just copying the binary and making it executable, maybe that was the issue i never installed it

The binary 7.4.13 should used for the Xcp-ng 8.3 release not for the 8.2.1.

The Problem from my earlier post is also solved, a new created vm was working. some copies from a another host does not work. perhaps there some driverconflicts in this Windows Vm.

8.2.1 with Tesla m10 will work with the correct drivers an patches.

I tried at first the driver from above:
NVIDIA-GRID-CitrixHypervisor-8.2-550.54.10-550.54.14-551.61
what doesn’t work.
After this I have found the newer Version:
NVIDIA-GRID-CitrixHypervisor-8.2-550.54.16-550.54.15-551.78
Now the Error on VM startup does not came up and the driver installation in the VM works.

The Driver packages what are specially for Xenserver8 are not installable on the Xcp-NG Version 8.2.1 because the different Base "https://xcp-ng.org/forum/post/80461https://xcp-ng.org/forum/post/80461"

now I get one VM working with a vGPU but a second one does not detect the mapped vGPU and the windows driver cant be installed
I am currently not sure why this happens, because a copy of the working one with another vGPU config will work.
The Xentools and Windowsversions are the same and the template also

the vGPU rpm is installable without any problems

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)

The Drivers "NVIDIA-vGPU-xenserver-8-550.54.10.x86_64.rpm" are installed and the system was rebooted. Now it is possible to select a vGPU via XOA for the VM.

Further the extracted vgpu file from the CitrixHypervisor-8.2.0-install-cd.iso was copied to /usr/lib64/xen/bin/vgpu and is executable.

The Start of the VM exited with:

"FAILED_TO_START_EMULATOR(OpaqueRef:0cc388f0-b606-469d-b68c-b4713c7f4abb, vgpu, Daemon exited unexpectedly)
"

Is there someone who has solved this Problem?

Platform:
HPE DL380 Gen10

It should be relatively easy to incorporate the Intel Flex GPU's, but I'm not sure if the newer kernels are required. That might be where the wheels fall off for now.

@mohammadm
I'm talking now about vGPU not passthrough

1. old drivers
2. no way to monitor GPU load
3. 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

I installed the Firepro S7150x2 yesterday without any issues. It's been about 24 hours, so far no issues. I do agree I am missing the nvidia-smi command to get a better overview.

Why is the support regarding vGPU so bad and mostly outdated

1. old drivers
2. no way to monitor GPU load
3. 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

@austinw no licenses, but a lot of troubles.....

Curious, what troubles?

@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.
