Its kind of funny to see a white paper touting running Oracle virtualized when unliked SQL Server, Oracle is not virtualization friendly from a licensing perspective. Oracle requires you license every physical CPU and core for a virtualized instance. This means you cannot use Oracle Standard Edition and instead have to use Enterprise since Oracle Standard edition cannot be installed on machine that is capable of more than 2 CPUs. In addition according to Oracle licensing terms since the virtualized Oracle guest is capable of using all physical CPUs despite being restricted in the VM guest you must license the number of CPUs in the physical host machine. If you have a 4-way 4 core host, this can easily run into several hundred thousand dollars. I guess that's yet another reason why Oracle is the number one DBMS ... BY REVENUE!
