When you create a domain via libxl you can pass an "xsdata" in the
libxl_domain_create_info which will cause extra xenstore keys to be
written.

This is not currently exposed via the xl tool though so if you are using
that you'll need to patch xl to read a key from the cfg file and
populate this field.
