OpenNEbula (former GridHypervisor) is a virtual infrastructure engine that enables the dynamic deployment and re-allocation of virtual machines on a pool of physical resources. ONE (OpenNEbula) extends the benefits of virtualization platforms from a single physical resource to a pool of resources, decoupling the server not only from the physical infrastructure but also from the physical location.

One advantage of server virtualization is the ability to rapidly provision new production environments. Automatic virtual machine deployment can significantly speed up the time to instantiate new services or reallocate resources depending on the user needs. This article focuses on the integration of SystemImager and Xen to create a totally open source framework able to manage on-demand deployment of virtual machines, such as physical machines, using a single centralized point of management. This approach allows to strongly reduce IT costs and simplify administrative tasks for enterprise data centers, even with a complex and/or reduced set of hardware resources, exploiting the dynamic-provisioning functionalities of SystemImager and virtualization advantages of Xen.
