Question

How is hypervisor different to docker?

Answer 1

The hypervisor runs at bare metal level, i.e. it controls the execution at the processor. From that perspective, OSes are the Apps running on top of Hypervisor.

On the other hand, the Docker daemon runs within an OS as a service and manage containers for you. So from docker perspective, containers are the apps running on your OS. The underlying control mechanism for both of these technologies is very different. One uses processor level instructions (hypervisor), other uses namespace and OS privileges.
