Sure, that makes it clearer.
I don't think there's a place to put arbitrary stuff that's then passed to
Xen. Am I right in assuming that the info would have to be available at
domain creation? I suspect you'd have to take a look at the details of domain
creation; how the functions in ocaml/xenops/domain.ml work and are used.
I don't have any experience of this part of the code myself though.
