OpenStack isn't a hypervisor! It's a system to emulate AWS locally that requires a hypervisor to present multiple system images.

You're right that it's not a hypervisor, but it's not an AWS emulator either. It's a collection of tightly coupled management layers for other open source projects that form a new, cohesive whole that can be competitive with AWS at a medium scale.
