H200 (GH100 NVL) on Proxmox VE – Only SR-IOV vGPU mode available, no mdev profiles?

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:
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:
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!
