I recently attended Oracle OpenWorld and was able to get a look at Oracle VM 3.0. The product has definitely undergone a facelift from the administration standpoint. The ability to manage the virtual environments through the VM Manager and Cloud Control 12c have been improved. The underlying product has also been upgraded from the standpoint that it is using a newer version of the Linux kernel and a newer version of Xen. The underlying architecture has not changed, and in my opinion does not need to change.
