You can think of containers as virtual Linux environments, implemented natively in Linux. Contrasted with Linux, the overhead is pretty minimal. Since Unix systems have some "virtualization" built-in natively, being multi-process, it fits nicely, imho. A unikernel is quite different. It allows you to create a bootable application with built-in operating system. One really doesn't have much in common with the other.
