Virtualization

The forerunner models of IBM Z® were the pioneers of virtualization. Today, virtualization technology can be found on any modern computer system.

From a security perspective, virtualization technology is valued according to its capability to isolate virtual machines from each other, ensuring that no virtual machine can observe or influence the computation or data of another virtual machine. The Start Interpretive Execution (SIE) technology of IBM Z and LinuxONE is the only virtualization technology based upon which a virtualization solution was implemented and certified according to Common Criteria at the EAL 5 level. It is the same SIE virtualization technology that is used by the z/VM® and KVM hypervisors to provide strong isolation between z/VM or KVM guests. This makes IBM Z and LinuxONE ideal systems to host competing tenants on the same machine.
