Minimal OS
----------
This shows some of the stuff that any guest OS will have to set up.
This includes:
* installing a virtual exception table
* handling virtual exceptions
* handling asynchronous events
* enabling/disabling async events
* parsing start_info struct at start-of-day
* registering virtual interrupt handlers (for timer interrupts)
* a simple page and memory allocator
* minimal libc support
Stuff it doesn't show:
* modifying page tables
* network code
* block-device code
- to build it just type make.
- copy image.final somewhere where dom0 can access it
- in dom0
# xi_create 16000 test
<domid>
# xi_build <domid> image.final 0
# xi_start <domid>
this prints out a bunch of stuff and then every 1000 timer interrupts the
system time.
