I've always felt that VMs are a sign that show that OSes have imperfectly abstracted the virtualization of their resources. A "design smell" if you will. When you get right down to it a window is a virtualization of a screen, a packet switching network is a virtualization of a fixed line, a process is a virtualization of a CPU, etc. (I can't remember who I'm quoting). The direction this is all heading (VMs, containers, unikernels, etc.) feels like confirmation of this to me. A series of corrections aligning our OSes with more ideal/virtual abstractions.
