For PCI hostdevs, <address type=3D'unassigned'/> + has a special meaning. A PCI hostdev must be assigned to the domain + with all the devices of its IOMMU group. If the admin so chooses, + it is possible to filter which devices the guest OS will actually + see, while the Libvirt domain is retaining ownership of all the + devices of the IOMMU group.
