GPU VM Passthrough - 3080Ti, No Such Device?

[archonitex]

Hello,

I've followed the guide for GPU passthrough. When I try to launch my VM, I get

error writing '1' to '/sys/bus/pci/devices/0000:02:00.0/reset': Inappropriate ioctl for device
failed to reset PCI device '0000:02:00.0', but trying to continue as not all devices need a reset
swtpm_setup: Not overwriting existing state file.
kvm: -device vfio-pci,host=0000:02:00.0,id=hostpci0.0,bus=ich9-pcie-port-1,addr=0x0.0,multifunction=on,bootindex=103: vfio 0000:02:00.0: error getting device from group 14: No such device
Verify all devices in group 14 are bound to vfio-<bus> or pci-stub and not already in use
stopping swtpm instance (pid 26429) due to QEMU startup error
TASK ERROR: start failed: QEMU exited with code 1

From what I can tell it is correctly bound to group 14 and the device does exists. I'm not sure what's missing?

Unsure if related, but I do see this dmesg logs:

vfio-pci 0000:02:00.0: Unable to change power state from D3cold to D0, device inaccessible

vfio-pci 0000:02:00.0: timed out waiting for pending transaction; performing function level reset anyway

Turns out I needed to update my BIOS. SOLVED
