I've been thinking about this, would it be feasible to have a first
patch that introduces all the boilerplate, like adding the domain
create option, wire the libxl bits, but doesn't actually add any
emulation at all.  Then further patches could fill in the emulation
slowly, starting with a patch to register the IO port handlers
(initially would be empty functions), and progressing from the basic
parts (uart initialization maybe?) towards the end implementation that
you have here.

Thanks, Roger.
