I currently have a headless server running Proxmox 6.1-5 with a Ryzen 7 2700X and I am trying to pass through a RX 480 to a KVM virtual machine. Motherboard: ASUS Prime x470 PRO (latest UEFI). My qm configuration file is here:
agent: 1 bios: ovmf boot: cdn bootdisk: scsi0 cores: 4 efidisk0: local-lvm:vm-102-disk-1,size=4M machine: q35 memory: 8192 name: win10-gpu net0: virtio=C2:10:DC:39:E3:CA,bridge=vmbr0,firewall=1,tag=50 numa: 0 ostype: win10 scsi0: local-lvm:vm-102-disk-0,size=200G scsihw: virtio-scsi-pci smbios1: uuid=1e178e39-dd5c-4feb-bbdf-7a285536125d sockets: 1 vmgenid: b98a2b51-3df7-4e17-b409-15bb4f0920b8 hostpci0: 09:00.0,x-vga=1,pcie=1 hostpci1: 09:00.1,pcie=1
I have tried to combine the
hostpci entries to just
but it makes no difference.
lspci reports both the VGA and the audio device using the kernel driver
vfio-pci. Windows just reports that it stopped the device with code 43 because it reported problems.
I have a display connected to the gpu and it does not show any picture at all since the vm is started. Installing the AMD driver for the RX 480 made no difference. All virtio windows drivers are installed.
I am at a loss - any ideas?
