Our Evaluation Tool for VMware Customers

vOneCloud OVA is free to download and use. This virtual appliance does not interfere with existing vSphere configurations, procedures, and workflows. This means that you can use it to evaluate OpenNebula, and if you decide not to adopt it, you can just delete it. vOneCloud is ideal for exploring OpenNebula’s main features (check its System Requirements before installation). If you are planning to build a large-scale cloud, are interested in the federation of multiple controller instances, or want to integrate your infrastructure with third-party components, customize the product, or manage open source hypervisors, it’s better if you contact us! 😉
