Pretty much this.
"You need to be the only on the box? OK!" *builds VM for app* "Here you go!"
89.9% of the time, none's the wiser, and the other 10% of the time, the vendor is basically "Oh, it's a VM. We support that too!" (It's not *quite* 100%, because there's always that ONE VENDOR who INSISTS they be the only tenant on that host/set of hosts because their code sucks that badly and they tend to be of the 'throw more hardware resources at the problem' types.)
