Oracle VM for X86 is a native hypervisor which is directly runs on the host’s hardware.This hypervisor is based on xen technology and it requires very small footprint on the hard drive to install it.Oracle VM server is directly installed on the baremetal computer and it contains the oracle VM agent to manage the communication with oracle VM manager. By default, this hypervisor system is called dom0 (Domain zero) which also be called privileged domain since it has direct access with hardware. Virtual machines will be called as domU which is unprivileged domain and doesn’t have direct control on the hardware.
This product is similar to VMware vSphere and you can see the comparison between these two products here.
