The operating system most relied upon by OpenStack users is Linux from a variety of distributors, and the hypervisor in greatest use is KVM (Kernel-based Virtualization Machine), according to the OpenStack 2014 Spring User Survey. The survey was conducted during April 2014 to gather information and feedback from organizations using OpenStack for development/QA, proofs-of-concept, and in production.
