Yes, CoreOS wants to be a host OS, but it's also a ripping good guest OS, because of its minimalism. I'm expecting most people to basically stick their app and nothing else (like, say, a full ubuntu environment) inside of the container. Hypervisor is the wrong word- that's what you'd call Xen, VMWare ESX or the host KVM kernel.
