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

[Parag Mhashilkar]

Hi,

Does OpenNebula EC2 interface support shutting down a VM from with in the VM itself and have the scheduler recognize that VM has been stopped/shutdown? How do we enable this feature? At Fermi, we have OpenNebula v3.2 and when the VM is shutdown it stays in the UNKNOWN state. Can OpenNebula get this ACPI shutdown info from virsh and handle the situation more gracefully rather than putting the VM in UKNOWN state?

Here is an example why I think something like this is useful:

When VMs are launched to perform certain tasks (classical equivalent of batch nodes), only the processes running in the VM know when the task is done and can shutdown the VM freeing up the resources. Running VM past the task life is wasted resources and controlling the lifetime of VM from outside is not always possible.

In case of AWS, it supports following which is very good feature to have when controlling the VMs in above scenario.
ec2-run-instaces --instance-initiated-shutdown-behavior <stop|terminate>

How do we achieve this with Opennebula?

Thanks & Regards
