I see two options: 1) they're using Hyper-V and exposing a small number of hypercalls to allow for rendering and interaction. 2) they've overloaded the Hyper-V name for a user space sandbox.

I'm really hoping for the former, as it'll mean they finally might expose a KVM-esque API. That would mean a drastic change for virtualization dev on Windows.

Maybe I'm misunderstanding the question, but the article clearly describes that they're using Hyper-V to launch a separate instance of the kernel and the browser in a "container" (which is later "discarded").
