Whether this is expected to work depends on the board model
(you don't give your QEMU command line). "exit the QEMU process"
happens when the guest powers down the emulated hardware,
so for this to work:
 * the h/w board being modelled needs to actually have a
   software-controllable powerdown feature (eg some device
   register the guest has to prod)
 * the QEMU model of that board needs to actually implement
   whatever the powerdown control is
 * the guest OS has to know about the control feature and
   use it
