Hi @luckyh , there is a conflict between the amd-iommu device and the PCIe slot.
qemu-kvm: -device {"id": "pcie-root-port-0", "driver": "pcie-root-port", "multifunction": true, "bus": "pcie.0", "addr": "0x1", "chassis": 1}: PCI: slot 1 function 0 not available for pcie-root-port, in use by AMDVI-PCI,id=(null)

Introduce `amd-iommu` device to guests. Configuration example:

    ```
    vm_iommu_model = amd
    iommu_$foo = ...
    iommu_$bar = ...
    ```
