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 once
|
|
every second the system time.
