I've written this code to automatically start KVM Virtual Machine at boot of host system, and stop Virtual Machine at shutdown or reboot of host system.
start on startup start on started networking and started qemu-kvm and started libvirt-bin stop on runlevel  kill timeout 70 expect fork pre-start exec /KVM/luc.sh prepara exec /KVM/luc.sh avvia pre-stop script /KVM/luc.sh ferma /bin/sleep 20 end script
luc.sh is a script with these functions:
- prepara() - prepare the environment
- avvia() - start KVM
- ferma() - shutdown KVM
It works except for the
sleep command. I need to delay the shutdown/reboot operation of the host system to wait for the guest shutdown to complete. In other words, I want insert a wait of ~20 sec after the
/KVM/luc.sh ferma command. It seems that the
sleep call in the upstart script is asynchronous. Is it possible to make a synchronous call in the upstart script?
