Hi

When using "xm save -c" to checkpoint a running domain, the hypercall 
SHUTDOWN_suspend should return 1, right?
However, it return 0 in my winpv driver. And i did not pass start_info 
as a parameter to the hypercall, is it necessary to write the magic word 
in start_info and then pass it as a parameter to suspend hypercall to 
support "xm save -c"?
There is also a suspend-cancel key in xenstore, and it's value is 1. 
What is it for? Need i do some process with this xenstore key?

Thanks
Annie.
