Wizard error: Failed to attach devices to VFIO

[veryheavypickle]

This issue occurs after booting up, after running the Wizard.

Running the command manually

~$ sudo bash -c echo "0000:01:00.0" > /sys/bus/pci/drivers/vfio-pci/bind
-bash: /sys/bus/pci/drivers/vfio-pci/bind: Permission denied

After allowing write permission

~$ sudo bash -c echo "0000:01:00.0" > /sys/bus/pci/drivers/vfio-pci/bind
0000:01:00.0: line 1: echo: write error: No such device

Hardware

• Ryzen 7950X
• 3090 Ti 24GB

Environment
This is running in a proxmox VM.

• IOMMU is enabled
• Nested virtualization is enabled
• GPU passthrough works flawlessly

I have both a windows VM as well as another linux VM that can utilise the gpu with no issues - one at a time of course. I can switch between the guest indefinitely and keep the host running 24/7 with no weird issues. Passthrough works as well as if running on metal, not even anti cheat detects it as a VM.

What I have tried

• Toggling GPU audio passthrough (the error changes to 0000:01:00.1 no perm instead of 0000:01:00.0)
• Toggling using GPU as display out on both golem-gpu-vm and the VM that build golem-gpu-vm
• Setting write permission on /sys/bus/pci/drivers/vfio-pci/bind the error is documented above
• Running the wizard in ssh terminal /usr/local/bin/golemwz-wrapper

What I believe the issue is
I believe the issue is proxmox related, since the GPU has already been passed through, it shouldn't expect to passthrough to a different level.

What I expect

• To be able to finish the wizard

Possible solution

• Skip guest creation in wizard, run the guest as a host and override the existing system where needed
