Sorry for responding to old thread, I later realized that Yun had already responded to Gabe's query.

soft_delete is invoked when "reclaim_instance_interval" flag is set to non-zero.
In this case, when delete command is fired, only the VM is powered off, and vm_state is set to SOFT_DELETE Other resources (like network, volume, and files created in instances_path etc) are cleaned up at later point via a periodic task.

hard_delete is when vm is "destroyed" (As opposed to power off) and resources are cleaned up immediately.
This is the default configuration
