Nova supports "soft deleting" instances when they are terminated. These
instances end up in a SOFT_DELETED VM state before they are cleaned up
after reclaim_instance_interval seconds. This is enabled by setting
reclaim_instance_interval to a value other than zero.

I'd point at some flag documentation that explains all that, but it doesn't
seem to exist.

Hope this helps,
