Why is OpenStack important?

OpenStack is an important part of the cloud landscape, since it provides a common, open standard through its API and allows portability between cloud environments.

How is KVM implemented?

How does KVM work? KVM converts Linux into a type-1 (bare-metal) hypervisor. All hypervisors need some operating system-level components—such as a memory manager, process scheduler, input/output (I/O) stack, device drivers, security manager, a network stack, and more—to run VMs.

Is OpenStack a hypervisor?

OpenStack is NOT a hypervisor. It is a “hypervisor manager” intended to remove the worry over hardware and its management. Flexibility is power — the amount of flexibility OpenStack has to offer from a design and deployment aspect is the power all infrastructure admins want and need.
