Hello,

I want to do GPU Passthrough to Windows 10 Machine on Proxmox Virtualization.

I followed the instructions in the link https://pve.proxmox.com/wiki/PCI_Passthrough

But when I run it in PCI-Express Mode, the virtual machine freezes or does not boot.

When I run it in PCI mode, the GPU-Z output is as attached, and the video card does not appear in the task manager.

Thanks.

Hello,

could you provide your vm config?

Run this command as root:
Bash:
qm config <vmid>

There is multiple guide on how to pass and forum have multiple topic on that. Mostly : disconnect the modem, install prox iso, put the 7-8 config files and you pass. But i rarely see dealing with the rom file. skip that for sure. If you never did this before , simply put a vm with xubuntu and boot . your card will pop up all working if basic setup are made.
