You can google about paravirtualization vs virtualization.

Oracle uses paravirtualized virtual machines based on Xen, when you paravirtualized the environment an special kenel is needed but in some cases you can get better performance. In a fully virtualized environment the virtual machine emulates all physical devices and no software tweaking is needed.

There are other concepts that applies to paravirtualized environments like Doms that are interesting to read. I really don't know about VMware Hypervisor, I have to update myselft about it.
