retrieve the PCI addresses of the destination host.
Update the ``LiveMigrateData`` object to include PCI device information (e.g.,
addresses, live migratable, managed). For the destination host by
introducing a new ``pci_devices`` field.
Update the ``LiveMigrateData`` object to include the PCI device mapping
between the source and destination device addresses. A new field,
``pci_dev_map_src_dst``, defined as a ``DictOfStringsField`` will
be added to the ``LiveMigrateData`` object for this purpose.
.. note::
The data structure required to store this information will be defined as
the implementation progresses. This specification will then be amended
accordingly.
Update the _live_migration_operation() function, with a specific focus
on the get_updated_guest_xml() function, to incorporate the PCI addresses
collected in the LiveMigrateData object into the destination XML file.
Update the _live_migration_operation() function, with a specific
