Hi John,

the stop event is not sufficient. I want to restart the VM if the guest 
initiates a reboot. The user of the VM expects that the VM is startet 
again after he/she clicks on reboot ;)
I want to use the --no-reboot flag to stop qemu and restart it on 
another vm host or to start it with another configuration (more/less 
RAM/CPU, a bigger HDD, etc...)

Best regards,
Dirk
