The team put a lot of effort in Medusa, and we want to thank you for the marvellous feedback received in the community forum, as well as the support given by the community to newcomers and people willing to upgrade their OpenNebula infrastructures.

It is also very welcome how people are keeping up to date with the latest releases. We hope you enjoying using OpenNebula as much as we enjoy developing it!

Integrations such as this one from UDS Enterprise gives indeed more flexibility to OpenNebula, with the ability to manage a VDI environment in an OpenNebula based infrastructure.
