The answer doesn't change. The question is not 'can we put it on a virtual', the question is 'does the server (virtual or bare metal) have enough resources'
These days, with the power of modern servers and the virtualisation technology available the questions shouldn't be 'can we virtualise this', the question should be 'is there a really good reason not to virtualise this'
