Thanks for your warm welcome and kind of mention for the preparation.

That's great, you have a powerful ARM server! Is there any document
about the process? Sooner or later we will need that.:-)

Currently, we are testing our patches on a Seattle based aarch64 server,
I also find an Odroid C2 aarch64 boxes, if it would be more convenient,
I will set up an environment on it too.

We are considering about the hackathon, but I found the register date is
closed on January 15th, 2017.

It's great! Currently we're using aarch64 Ubuntu, most of OCaml packages
can be installed directly except some mirage-solo5 packages which are
depending on the ukvm and solo5 kernel. :-(
