Currently, Intigua supports auto discovery of machines from VMware vSphere and Amazon AWS. Support over OpenStack and Hyper-V is planned. Until then you can still work with servers running on OpenStack or Hyper-V in the same way that we can work with Physical Servers, which means you manually add the server to the list of Servers Intigua is managing. From then on the full functionality of Intigua is available, its just the auto discovery that is not usable (and some specific optional protocols used for communication such as VIX, we will fall back to normal network protocols instead).
We can also integrate with your existing provisioning and orchestration tools like vCO and vCAC, and utilise the Intigua REST API to automate the addition of servers.
