The OpenNebula Project has just announced the Beta release of vOneCloud, a CentOS Linux virtual appliance for vSphere that contains all required OpenNebula services optimized to work on existing VMware vCenter deployments. vOneCloud is for companies that want to create a self-service cloud environment on top of their VMware infrastructure without having to abandon their investment in VMware and retool the entire stack. vOneCloud deploys an enterprise-ready OpenNebula cloud just in a few minutes where the infrastructure is managed by already familiar VMware tools, such as vSphere and vCenter Operations Manager, and the provisioning, elasticity and multi-tenancy cloud features are offered by OpenNebula.
