I would strongly recommend reading the blog post from Steve Herrod, VMware's CTO where he talks about the deal. This covers a lot of the technical vision and value proposition that has been the technical focus for SpringSource since the deal closed.

Regarding the case specifics that you are discussing about Java and DB performance on a VM, I know that VMware has a Java performance expert focused on that directly. Send me a private message in the forum and I can put you in touch with him.
