Guys

I patched xl to have "reboot" and "shutdown" commands.
I tested this with hvm domains with and and without pv drivers seems to 
work, of course the os level reboot and shutdown will only happen if 
there are pv drivers with the dom U.

Also the libxl_domain_shutdown was not working for hvm guests without pv 
drivers, I did a small patch to that as well. (same way xend shutdown 
works used || instead of a && ). I would appreciate if someone can test 
this more with hvm and pv domains.

Let me know what  you think
