Hey guys, new to Level1Forums.
I’m attempting to spin up a virtual machine (virt-manager) with PCI pass-through of my Nvidia GTX 1080 to a Windows 10 VM. I followed a couple of super useful tutorials on Youtube (Would be linked, but they dont like that here I guess). My eventual goal is to game on the VM and try out Looking Glass. Right now I have a dual boot setup for gaming titles that have bs DRM or anti-cheap software.
I’m getting to the very end and come up with this error.
Unable to complete install: 'unsupported configuration: host doesn't support passthrough of host PCI devices'
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/asyncjob.py", line 75, in cb_wrapper

libvirt.libvirtError: unsupported configuration: host doesn't support passthrough of host PCI devices
Specs and configuration are as listed:
Manjaro 20 Gnome (latest release)
Intel Core i5 6600k @ 4.6Ghz
16gb of RAM
Gigabyte Z170 mobo
PNY Nvidia GTX 1080 8GB
A couple of Samsung 500gb SSDs,
WD 1TB HDD
And before anybody asks, yes VT-d is enabled.
Something I noticed while following either of those two tutorials, when I ran the command ‘sudo dmesg | grep -i vfio’ , it returned with (error -22)
[ 1.314392] VFIO - User Level meta-driver version: 0.3

I’ve tried following the tutorials with close detail about 4 or 5 times now and i’m still tripping up on something. Any help would be greatly appreciated.
