Power9 supports a new feature called Protected Execution Facility; also
known as Secure Memory Facility.
This feature enables a higher privileged execution mode called Ultravisor mode.
When enabled, Hypervisor can access some system resources only through
Ultravisor using ucalls. Paravirtualize the hypervisor to use the services of
the Ultravisor. The PEF along with the Paravirtualized hypervisor and the
Ultravisor, enables Secure Virtual Machines.
