Hi all,
I'm sure this has been covered elsewhere, but I can't seem to find it. I just finished building my TNS server - I'm trying to get a Windows VM set up for it, but I'm getting the following error message when I try to passthrough the GPU (I have two):
"Error while creating the PCI device. [EINVAL] attribute.pptdev: Not a valid choice. The PCI device is not available for passthru: Following errors were found with the device: Unable to determine iommu group [EINVAL] attribute.pptdev: IOMMU support is required."
The extended error is:
How do I fix this?
This may be related: I have two GPUs in the machine - an Nvidia Quadro A400 (which I want to pass through) and an old AMD Radeon, which I installed because I thought I needed a separate GPU for the system (which is also weird to me). Truenas sees the AMD, but seems to only want to show output on the Nvidia. Is there a way to change what GPU Truenas reserves for itself?
Thanks! Will.
