V8 is just the JavaScript runtime, not a full browser environment (i.e., no DOM, etc.) If you want to use V8 headless, you can either use NodeJS or you can link it into your own C/C++ code to run JS scripts, which is what I did a while ago for a project that needed a scripting hook. If you want to run a full browser environment headlessly, take a look at PhanthomJS or SlimerJS, or use one of the fake DOM thingies for Node.
