July 28, 20241 yr I have been going at this for awhile now. I can not get my p40 to switch from tcc to wddm in a VM I have. The Vm sees the gpu and I could use it as a compute card just fine. No method I have tried to change it from tcc to wddm works. I was wanting to make that card the primary card for that VM headless and then remote into it. Any help would be appreciated!
July 28, 20241 yr Community Expert What os is vm running does this not work? nvidia-smi -i 0 -dm WDDM
July 28, 20241 yr Author It came back as “option wddm is invalid for -dm” I am running windows 10 on the vm. I shouldn’t need a vgpu on unraid for it to work correct? Barebones and pass through shouldn’t require a vgpu driver to my understanding?

July 28, 20241 yr Community Expert I think you may need vgpu drivers to chnage, This for p100 but guess will be same for p40 https://stackoverflow.com/questions/56865611/how-to-enable-wddm-on-nvidia-p100
July 28, 20241 yr Author is vGPU drivers supported by unraid yet? Are you meaning like a GRID driver? I have GRID drivers that I have tried installing on the VM but it says my hardware is not compatible with the vGPU drivers?
July 28, 20241 yr Author I have tried the Data center driver as well as a quadro workstation driver as well; which will install but does the samething. This is what the GRID driver says.
