Paravirtualized Xen guest kernel is on ring1 so Xen must forward system calls 
to it and then guest kernel replies with a hypercall to Xen.
How does a system call work on QEMU? 
When a guest kernel wants to directly access to device or perform a sensitive 
but not privilege instruction, what's happened?

Thanks
