Oracle is a very bad test for virtualization. First, Oracle is very disk-intensive, to the point that they recommended their own file system for many years and still recommend that the database is separate from the application itself. Second, Oracle has an excellent cluster management system as it is and as such, really should be left to do its own virtualization. The real benefit is: 1. Bunching up low resource systems. We've all seen those applications that are only used lightly, but take up their own server. 2. Failover. A server dies? Get those processes moved to other machines to spread the load in minutes while the server is fixed.
