PCI(e) Passthrough VM not turning on laptop TASK ERROR: 'device' assigned more than once

[izarma]

Hi!

I'm Running Proxmox with dualboot on my laptop and wanted to try out PCI(e) passthrough, it has an amd processor and I enabled iommu. I'm passing through devices in the network gorup of the Nvidia GPU and the AMD iGPU but I get the error given in the label with the device name of my nvidia gpu. What should I do?

You might be passing through separate functions of the same device and enabling All Functions on each (instead of passthrough of the device once with All Functions). Please show the VM configuration using qm config $VM_ID_NUMBER.
Also make sure to check your IOMMU groups: https://pve.proxmox.com/wiki/PCI_Passthrough#Verify_IOMMU_isolation
