Hi
   Is there any site that provide the whole flow of the xen source code and
how it works in term of the source code?

You mean call-graph of  the different functions? I think doxygen should
do it but I am not entirely sure how to set that up.

As far as I know there is only the source itself and the standard tools
which you have available on Unix/Linux system such as grep and cscope
(or the tags software of your choice).

You may find http://wiki.xen.org/wiki/Asking_Xen_Devel_Questions useful
in framing your questions for the list in the future.

Unfortunately not.  There is a book about Xen below.  It's now a bit
dated, but it might give you an idea what's going on at a high level:

http://www.amazon.com/The-Definitive-Guide-Xen-Hypervisor/dp/013234971X/

I mainly use grep and gtags when I'm finding my way around a new piece
of software.  Here is a rune that I've found particularly useful:

find . -name "*.[cSh]" | xargs grep -H [whatever]

P.S. If you do get the book, don't try to implement the example
scheduler.  For one, the code in the book is buggy and doesn't work.
For two, schedulers are one of the most difficult parts of the system
to debug, so it's not a good place to start. :-)
