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. Passing address type <code>none</code> + 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>&lt;address type='none'/&gt;</code> is an invalid address + type for all other device types. + <span class="since">Since 5.10.0</span> + </dd> </dl> <h4><a id="elementsVirtio">Virtio-related options</a></h4> -- 2.21.0
