+ <dd>For PCI hostdevs, <code><address type='unassigned'/></code>
+ 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. Using this address type in such cases
+ will tell Libvirt that the device must not be assigned to the guest.
+ This avoids scenarios in which the admin might be compelled to use
+ a ACS patch to remove the device from the guest.
+ <code><address type='unassigned'/></code> is an invalid address
+ type for all other device types.
