hi,
Does anyone know of any document which explains internals of xen
(typically about creation of domains from perspective of process
creation and system programming)?
The aim is to call xen api's in a program to automate the process of
creation/shutdown/migration of domains.
You'll probably want to call into some of the tools; the backend libraries
of the xm tool are likely to be best. If you these instead of the lowlevel
Xen APIs you get a lot more work done for you. Alternatively, you can talk
the Xend management protocol directly, either over a Unix domain socket or
a TCP connection.
Of course there is also the quote that came up last week "the roads are the
best map", i.e. the source code generally is the most up-to-date reference
;-)
Perhaps the Xen Interface Manual? Covers Xen 2.0, 3.x is a work in
progress.

You're probably going to be most interested in Appendix A, "Xen
Hypercalls", particularly A.8, Inter-Domain Communication.
We're actively looking at getting the interface documentation into a good
state - ideally in time for around 3.0 (at which point the interface will
be stable and supported for the foreseeable future). Stay tuned folks ;-)
Cheers,
Mark
