Hello all!

UPDATE ----- I decided to just plug in a second GPU for Proxmox and put my 2060 to the 2nd PCI-E Slot and it works... I would recommend anyone who has issues with GPU Passthrough, just buy another crappy GPU for Boot.

Long time Unraid User here wanting to venture more into VMs than just NAS, set, and forget setups.

So I have been at this for a few days and followed plenty of tutorials, even the wiki ones created by Proxmox.

I had my GPU working once on one VM and then I deleted that VM and it never worked again.

I have repetitively started from fresh, following guides on what to do but I get stuck at one part.

1. Installed Proxmox
2. Setup GPU Passthrough the following guides
3. Setup VM

VM sees the card in Device Manager and installs Nvidia drivers. Reboot, Nvidia drivers are then not installed and error 43 still exists.

Computer Specs
CPU - AMD 3950x 16 Core
GPU - MSI 2060 - I am only using one card
Motherboard - X470 AORUS GAMING 5 WIFI
RAM - 32 GiG 3200mhz

Setup

Code:
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet amd_iommu=on iommu=pt pcie_acs_override=downstream,multifunction nofb nomodeset video=vesafb:off,efifb:off"
GRUB_CMDLINE_LINUX=""

Code:
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd
