Hi all,

I’m testing **NVIDIA GH100 (H200 NVL)** GPUs on **Proxmox VE 9.0.3** with the vGPU driver package:  
**NVIDIA-Linux-x86\_64-570.195.02-vgpu-kvm.run**

**Current Situation:**

After installation, I’m experiencing the following issues:

- `nvidia-vgpu-mgr` service fails to start with the error:

```auto
Failed to attach device: 0x59 (gpuId 0xae00)

```

- `/sys/class/mdev_bus/` and `/sys/bus/pci/devices/.../mdev_supported_types/` directories are missing
- `nvidia-smi -q` shows:

```auto
Virtualization Mode : Host VGPU
Host VGPU Mode : SR-IOV
sriov_totalvfs : 32

```

**Observations:**

Based on these results, it appears that the **H200 only supports SR-IOV-based vGPU virtualization** and not the traditional mediated device (mdev) mode. When testing under Proxmox, the `pve-nvidia-sriov@` services work correctly and VF devices are created successfully, but no mdev profiles are available, and `nvidia-vgpu-mgr` consistently fails to attach the device.

**Question:**

Can anyone confirm whether **mdev-based vGPU is deprecated or unsupported** on GH100/H200 series GPUs? Is there any **official documentation** or compatibility matrix that clarifies which GPU models still support mdev versus SR-IOV-only configurations?

Any guidance or links to official NVIDIA documentation would be greatly appreciated.

Thanks in advance!
