Currently, OpenNebula does not implement the whole EC2 API set and some
implementation depends on certain calls (i.e security groups), we are
working on extending the EC2 support, we have already improved it in
OpenNebula 4.4, but security groups are still not supported

You are right. You can integrate different OpenNebula instances using the
EC2 API. The problem is that the EC2 client library does not allow you to
specify a custom url, you have to use one of the existing ec2 endpoints.
Therefore, you have to modify the library to use custom endpoints, or
redirect ec2 urls to a different IP.

As I said in the previous mail it would not be difficult to implement a
Deltacloud driver, therefore you could interact with OpenNebula since
Deltacloud currently support it or interact with any of the providers that
Deltacloud supports.

Hope this helps
