No it doesnt. And the presentation is not very accurate. Rump kernel is a proper unikernel (based on the proven NetBSD kernel) but actually running as a library operating system, in the same address space as the single application it is linked to. You compile and link the kernel library and application into a single elf file. OSv is a single address space too, it just tries to pretend to look more like a normal OS. I think Drawbridge is a proper unikernel too. So the examples in the slides are simply wrong.

PS no idea who downvoted you, there is really no point in mentioning it.
