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. - to start it do the following in domain0 (assuming xend is running) # xm create domain_config this starts the kernel and prints out a bunch of stuff and then every 1000 timer interrupts the system time.
