This script uses Qemu's monitor interface. The monitor interface has a
system_powerdown command that can be used trigger an event to cleanly shutdown
the system. Unfortunately this does not seem to work (Please check if this works
for you). One work-around is to configure the guest's init to halt the system
when it receives an ctrl-alt-delete as shown below
File:/etc/inittab
- ca:12345:ctrlaltdel:/sbin/shutdown -t1 -a -r now
+ ca:12345:ctrlaltdel:/sbin/shutdown -t1 -a -h now
And then use the following monitor command, to generate a ctrl-alt-delete
sequence, when the system has to be halted.
sendkey ctrl-alt-delete
