The 'their' reference is to Nutanix whitepaper.
So you're saying Acropolis is another vitualization platform? I didn't understand that from the white paper. If that's the case, I would still be optimistic in thinking it could work. But I can't give a clear yes/no until I've seen test validation. There's currently no plan in the roadmap to test/support Acropolis, so it'd be a feature request to submit to the ideas portal.
If it is an option, I would suggest going with VMware or HyperV which are tested and supported install models. Though, for anyone who does try Acropolis, I'd be interested if there's any performance improvements since we guide a 20% resource increase for the virtualization layer overhead.
