Yes, it works!  Just a couple of remarks:

- `vmnet` and `mirage-net-macosx` (not the x at the end) do not seem
to have trickled in to the default http opam repo yet.
- make sure to run the example under sudo, otherwise the unikernel
just seems to hang without any output

Thanks for this, it's great.

Best wishes,
Nicolas
