Hi,
I am trying to passthrough the primary GPU of my host to a VM. Passthrough is enabled and I can add it as a PCI device to the VM.
However, when I try to start the VM, I get an error saying that:
Failed - Module 'DevicePowerOn' power on failed.
- Module 'DevicePowerOn' power on failed.
- Failed to register the device pciPassthru1 for 129:0.0 due to unavailable hardware or software support.
- Failed to start the virtual machine.
And dmesg reads
PCIPassthru: 2938: Can't use virtual IOMMU with devices with dependencies sdbf=0000:81:00.0 which refers to my GPU
Any ideas what I could do to make this work would be much appreciated.
(I have tried making the GPU not the primary GPU in my host but although I select another GPU in the video configuration of my bios, it still is initialized and used as primary GPU. I can passthrough the other GPU in my host but I need that one for another VM.)
