pci passthrought, nvidia, win7: code 43

[samontetro]

I'm trying to use pci passthrought for an old nvidia GeForce 9300 GE GPU in a win7 VM.
The GPU is detected in the guest os, driver is installed and updated but I still get a code 43 error.
I haven't more detailed information and this peripheral is disabled in the VM

The config is based on the tutorial https://pve.proxmox.com/wiki/Pci_passthrough

This is my VM config:

# cat /etc/pve/nodes/proxmost2/qemu-server/101.conf
boot: cdn
bootdisk: virtio0
cores: 4
cpu: Haswell-noTSX
ide1: local:iso/virtio-win-0.1.126.iso,media=cdrom,size=152204K
ide2: cdrom,media=cdrom
memory: 16384
name: wincao1
net0: virtio=86:7D:D8:C1:B6:D9,bridge=vmbr9
numa: 0
ostype: win7
scsihw: virtio-scsi-pci
smbios1: uuid=b69dd731-b43e-4f69-84da-68d2f772111d
sockets: 1
virtio0: cephstorage:vm-101-disk-1,size=96G
hostpci0: 04:00.0

Proxmox VE is 4.4-12

Any suggestion is welcome, my aim is to test a CAO application speedup with a GPU in the win7 VM before buying a more powerfull GPU if it works.

Hi,

you have not set

machine: q35

also uefi must be use as bios type

Thanks for your reply Wolfgang,
I have not understood this was requested in the last sections of the tutorial....
If I set the BIOS to UEFI (the VM was installed with default Bios settings) does it mean I must reinstall the VM ?
I had set "machine: q35" (without understanding what it was meaning) and the VM was not booting anymore, may be because of the BIOS settings.
Moreover with x-vga=on the console was not working anymore so I removed this config.
I check quikly (one user is remotely testing the application in this VM at this time)

AFIK you have to install Windows new. May be there is a hack but I'm not a Win user.

machine: q35"

This is a an other HW design what is required for pass-through
