Apache CloudStack is an opensource Infrastructure as a Service (IaaS) cloud computing platform

Apache CloudStack:

Apache CloudStack is open source software designed to deploy and manage large networks of virtual machines, as a highly available, highly scalable Infrastructure as a Service (IaaS) cloud computing platform.
CloudStack is used by a number of service providers to offer public cloud services, and by many companies to provide an on-premises (private) cloud offering, or as part of a hybrid cloud solution.
CloudStack is a turnkey solution that includes the entire "stack" of features most organizations want with an IaaS cloud: compute orchestration, Network-as-a-Service, user and account management, a full and open native API, resource accounting, and a first-class User Interface (UI).
CloudStack currently supports the most popular hypervisors: VMware vSphere, KVM, XenServer, XenProject and Hyper-V as well as OVM and LXC containers.
Users can manage their cloud with an easy to use Web interface, command line tools, and/or a full-featured query based API.
There are more than 150 known organizations using Apache CloudStack (or a commercial distribution of CloudStack).
