Hello,
I would like to raise a topic regarding possibilities when metadata could be modified on instance. We noticed that instance metadata could be modified only when vm_state is set to following values: * active * paused * suspended * stopped Found: https://github.com/openstack/nova/blob/master/nova/compute/api.py#L3916-L3920 https://github.com/openstack/nova/blob/master/nova/compute/api.py#L3905-L3908 >From time to time it is needed to have instance in rescued state. Scenario: VM is rescued and special metadata attributes need to be set to allow cloud-init to act specifically for rescue mode. Metadata data should be available only during rescue mode. Question: what kind of impact could be observed when checks for instance state will be modified for methods: update_instance_metadata delete_instance_metadata Thank you, Cheers, Pawel
