Has anyone successfully used an Intel Arc Pro B70 on a Windows VM?
I bought the Intel Arc Pro B70 on launch day to replace an aging Nvidia Tesla P40 in my Proxmox server. After updating to a supported kernel, Proxmox was able to detect the card and load the xe driver.
I did a full GPU Passthrough to a Windows VM and the full driver installed to get any firmware updates. After reboot the card shows as detected but failed with a Code 43 and the Intel Pro Graphics Software reports an unsupported system configuration.
I then went back to Proxmox and loosely following the Level1Tech's guide I was able to split the B70 into 4 vfs. I attached 3 of the vfs to various Linux VMs and after faffing around with kernel updates I got them all seeing the vGPUs. Plex running on one of the VMs was able to hardware transcode a 20GB movie in about 5 mins.
Going back to the Windows VM, I attached the 4th vf and booted. It saw the vGPU as an "Arc Pro B70 Graphics" but the driver still fails with Code 43 and the Intel Graphics Software reports the same unsupported system configuration.
So far the GPU has failed to work on a Windows VM with full passthrough or as a vf. Has anyone been successful getting a B70 to work on a Windows VM?
