And it is a difficult balance to strike... providing the full v* feature set would have a massive cost. My user community is looking for an on-ramp to cloud. They agree it is the right way to go in the longer term but it has to be a journey, not a 'leap from the lion's head' moment. This has a set of steps from their current service consolidation environment towards a full cloud model. I would find this discussion with my users much easier if we can offer basic VM restart/live migration along the way.
