Not yet. I just added some debugging output to help my development.
I'm still working on Mini-OS management module, which is making few

Another strange thing is, though we get a wrong caculation result here,
subsequent cauculations work fine. That means we initialize MM with
proper arguments, which is proved by my trace in /* build_pagetable() */.

I'm doing development with VMWare, because I don't have another machine
to communicate with XEN through a serial port. I don't know if this will cause
any side effect.

I'm wondering if you can offer any advise, I'll be happy to hear that.
