[libvirt] [PATCH] qemu migration: assign addresses in xml passed as parameter

[Nikolay Shirokovskiy]

Usecase:

1. define domain with xml A where addresses are not set
2. migrate with '--xml A'

You get ABI incompatibility because we comprare xmls with addresses
set and not. This patch assign addresses in parameter xml so
the comprasion is fair.
