We had a lively discussion at the summit about this feature: https://etherpad.openstack.org/HavanaMothballServer The entire value proposition of this feature is that resources are the same on unshelve. I don't see any way to do this outside of nova. Also, it bears mentioning there is room for optimization on the unshelve using something similar to live-snapshotting [1].
