The machine structure has another (optional) attribute: default-ram-id, which specifies the alias of the default RAM object. While the alias is private, it can never change in order to not break migration. QEMU uses the alias when allocating regular, not NUMA memory. In order to switch to new command line and maintain migration, save this ID.
