Hello Boris -
This forum is for questions specifically related to using the Database Cloud Service, so I don't know if you will get an answer to your question here, which concerns using an Oracle Database in a different way.
Sorry, but I don't know of the appropriate forum or venue for your question.

It's been reported that an upcoming version of Solaris will have native support for OpenStack. Red Hat already supports OpenStack and OpenShift so you may have better luck going that direction.
Like Rick, I'm not aware of a specific "cloud implementors forum". Internally, Oracle has lots of material on implementing cloud, using any platform at all, although obviously we feel Engineered Systems are the most cost-effective solution for many customers. Are you interested in IaaS i.e. virtualised hardware, or PaaS i.e. DBaaS? They should not be confused, neither is required for the other, in fact, using IaaS to implement "DBaaS", as the OpenStack trove API attempts to do, is probably the most counter-productive way to go about it. Define the business-visible services you will be offering, and then design the most efficient means of supporting them. That way you gain from economies of scale, and set up appropriate management systems that address issues like patching, security, database virtualisation and so on.
