So, let's say we're checkpointing 3 tasks in a s390-kvm.
Now we restart them outside of kvm.  Some process will
fork(), exec() some restart program, which will in turn
fork() twice, then each of those programs will call
sys_restart(), read the info pertaining to the checkpoint
task they are to re-create, and set themselves up.

Should the s390_enable_sie() then not be correctly set
by the system automatically?  So whether or not I'm
restarting in kvm, the kvm_arch_create_vm() for s390
will have been called?

Or do I misunderstand?

thanks,
