In simple terms Openstack is orchestration software which uses VMM for VM.

Regardless of features in the area of networking and strage virtualization, OpenStack Compute project provides the following advanced features that can not be found on VMMs:

  • heterogeneous hypervisor support
  • Massive Scalability
  • Workload Scheduling(Distributing the workloads between different hosts to acheive better performance)
  • Multi-Tenancy
  • Virtual Machine Image Management
  • Broad Range of Compute APIs
  • Self-Service Portal
  • etc

OpenStack intended to act as a higher level than virtualization. Yes it can interact with virtualization/containarization systems (such as KVM, ESXi, Xen, Docker...) through drivers, so you will have an universal interface (web or CLI) to manage your VMs. But OpenStack can do more, it's a set of projects linked together to provide you a full cloud system, comprehensive of virtualization, network as a service, object storage and much more.
