What would the benefits of using a virtualized server for a relatively small (in terms of server needs) site like HN be? The way I see it so far, is that virtualization is mostly beneficial for hosting companies that can provide cheaper hosting and have better isolation and easier resource allocation. But I can't think of any big benefits for the site owner, assuming they can afford a dedicated server, and I can see downsides of virtualization, so I am genuinely curious if I miss something.
