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.
