A question I tend to ask my customers almost always is what their current state is regarding IT transformation and journey to the cloud. Of course such a strategy does not work very well on bare metal and some kind of isolation between services and physical hardware is required – which naturally includes virtualization, as well as the use of some kind of container technology, as-a-Service paradigms, changes in IT administration and operations etc.
Nearly always the answer includes “We already virtualized everything! … Well, ehm, except Oracle….”
TL;DR: There are no more roadblocks for virtualizing Oracle, including license issues. See the last section “Mythbusting” of this post for a summary on myths and truths.
