I don't think anybody else on this list has looked in to suspend before.
So I have two suggetions:
1) look into the Xen code that implements this hypercall. In particular,
you're looking for SCHEDOP_shutdown in xen/common/schedule.c
2) if you don't understand that, you can ask specific questions on
xen-devel@xxxxxxxxxxxxxxxxxxxx

ignored, and may be an artifact from old code. If so, you should submit
a patch to xen-devel to remove it.
