please do last proxmox updates from pve-no-subscription repository.

qemu-server >= 4.0-43 should fix it

I have uninstalled and reinstalled the drivers on the guest and still getting code 12, code 10 before I install the driver

Edit: I would also like to add that I do have to install windows 7 without the passthrough enabled, it freezes at the "starting windows" screen. I was able to get windows 10 to passthrough during install just fine. but win 7 freezes

 

[spirit]

can you send your /etc/pve/qemu-server/vmid.conf file ?

can you send your /etc/pve/qemu-server/vmid.conf file ?

If I use this config it freezes at the windows is loading screen while trying to install windows

bios: ovmf
boot: dcn
bootdisk: sata0
cores: 2
cpu: Haswell
hostpci0: 01:00,pcie=1,x-vga=on

machine: q35
memory: 4096

usb0: host=1-4
usb1: host=046d:c247

however if I install windows without x-vga=on I can install windows and the nvidia drivers using console but then nvidia gives me code 10/12 with this configuration and if I re-enable x-vga=on after installation it once again freezes at windows loading screen

bios: ovmf

on a side note I have also tried ostype:win7 and ostype:win8

 

[spirit]

,x-vga=on is needed, because it's disabling hyperv-v features and mask kvm feature in cpu,which is needed for geforce driver.
I don't see any reason why it could block windows boot.




Do you have tried without machine:q35 and ,pcie=1 ?

bootdisk: sata0

also, uefi (ovmf), don't work very well with win7.
I think you should try with win > 8

 

[Soulgriever]

I decided to give up windows 7 for now and have two VM's running on windows 10, I will try without pcie when I get home.
