Writing a Xen book

Writing a Xen book

[Matt Frye]

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.

xc_linux_save(): which context does it get invoked?

[T S]

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
