fix #3784: config: Parameter for guest vIOMMU + test-cases vIOMMU enables the option to passthrough pci devices to L2 VMs in L1 VMs via Nested Virtualisation and adds an extra isolation. Uses the new property-string from the "config: define machine schema as property-string"-commit to add the viommu option to the machine parameter. Currently there are two vIOMMU implementation in QEMU to choose: intel or virtio Virtio-iommu is more recent but less used in production than intel-iommu. The assert_valid_machine_property function prevents using intel-iommu with i440fx.
