[one-users] Shutting down a VM from within the VM

[Sharuzzaman Ahmat Raslan]

Hi Parag,

I believe OpenNebula need to have human intervention to really determine
whether to remove or not the VM that it has deployed.

I also think that you can write a script that signal or call OpenNebula
command as soon as the task finish, to shutdown the VM. Or if direct
calling command not possible, maybe your application can write some status
in a database, and a script in OpenNebula read that status and make
decision from it.

Thanks.
