The issue is, create_domain will eventually call freemem.
If autoballoon is set, due to dom0_mem= for example, all is fine.
If memory has to be freed, libxl_domain_need_memory will get an
incomplete b_info. Somehow the new libxl__domain_set_device_model
must be called for the d_config returned by parse_config_data.

How should this be fixed?
