Hi,
I realize this is not a support list and apologize for the
interruption. I am currently working on a book about Xen and am
looking for community contacts who can assist me with questions,
understanding, etc. Are there any Xen community ambassadors?
Regards,
Matt Frye

I would highly suggest hanging out on IRC on one of the Xen channels.
Either ##xen on freenode or #xen of OFTC.

Hello,
Thanks to Ewan Mellor, I managed to get some understanding of the flow of
events when "xm save" is called. But I still don't understand which kernel
is doing what.
In my setup, i have the hypervisor and on top of it there is Dom-0 and a
Guest kernels running. From Dom-0, I invoke "xm save" on Guest. This results
in calling some python code which (A) waits in one thread to see in xenstore
'suspend' value for control/shutdown, and (B) calls xc_save() in another
thread. xc_save() calls xc_linux_save().
My question: Does (B) get executed in Dom-0 or Hyperviser? If I change
xc_linux_save.c, should I compile xen, xen0, or xenU kernel to see the
effect?
thanks,
- Ts
