It's because your GPU (And it's 3 child devices) weren't bound to the vfio-pci driver first, or the PCI slot that it's plugged into is shared with other devices. To reduce post size I've linked the XML, lscpi -nnv results, and IOMMU groups from pastebin So I'm just looking for help at this point, trying to get this leg of the journey off the ground. Please ensure all devices within the iommu_group are bound to their vfio bus driver.

The card has 4 devices, all of which are being passed through in virt-manager 33:00.0 VGA compatible controller : NVIDIA Corporation Device (rev a1)ģ3:00.1 Audio device : NVIDIA Corporation Device (rev a1)ģ3:00.2 USB controller : NVIDIA Corporation Device (rev a1)ģ3:00.3 Serial bus controller : NVIDIA Corporation Device (rev a1) To preface the issue I'm having: I managed to get the VM working with Spice and QXL for debugging purposes, when I was able to verify that everything was, in fact, working I had removed those two devices in hopes that RTX 2080 being passed through would take over, however switching inputs did not give me any display despite virt-manager showing the VM running. Seagate 510 M.2 in second m.2 slot (host) Seagate 510 M.2 in first m.2 slot (guest) System:Ģx 16GB RAM Modules (using hugepages to preallocate memory)
Before I start allow me to thank everyone here as this sub has helped immensely in my journey to getting a Win10 VM running in the first place on a passthrough NVMe drive, many of the answers i was looking for when I did run into problems lead me here.
