Saying that because fsync() doesn't work in AWS that it won't work 'in the cloud' is much like saying that because you can't take a cheap sedan to the bush that a 4wd can't possibly exist.
Google can't exist (well) on top of AWS as AWS is designed for the deployment of (qusi)stateless applications. Saying that you can't build a data intensive application on top of it is like saying that your machinegun sucks at grating cheese.
OVM was designed to run a search engine origionally (darkmatr, now defunct due to lack of comparitive profitability), so you could quite easily build google on top of it. It wouldn't surprise me if google would work really well on top of that stack.
