OpenNebula 4.4 KVM Sandbox

The sandbox is a CentOS 6.3 virtual machine image with a pre-configured OpenNebula 4.4.0 front-end, a virtualization host using QEMU ready to execute virtual machines, and prepared images to offer a complete and rich cloud experience. Optionally other physical worker nodes using any of the hypervisors supported by OpenNebula can be enrolled to build small-scale cloud infrastructures. Users are able to log into an OpenNebula cloud, peer the managed resources, and launch instances of virtual machines without the hassle of configuring a physical infrastructure.
