Usecase:
1. define domain with xml A where addresses are not set 2. migrate with '--xml A'
This use case is incorrect. To make sure the ABI compatibility checks pass, you should take the XML back from libvirt. In addition to assigning PCI addresses, libvirt may add some implicit devices (such as USB controllers, keyboards, balloon device, ...) or even reorder some elements in the XML.
That said, you should follow the steps below:
- define a domain using A.xml - start the domain - fetch the updated XML (virsh dumpxml --migratable >B.xml) - change whatever you need in B.xml - start migration with --xml A.xml

Ok, I see. Thank you for clarification. Nikolay.
