KVM for IBM Z® and LinuxONE is an open-source alternative to the IBM z/VM hypervisor for the virtualization of Linux® workloads on IBM Z and IBM LinuxONE systems.

Faced with rising data demands and security concerns, Kernel-based Virtual Machine (KVM) open-source virtualization can help you to effectively meet these demands on your IBM Z and LinuxONE systems. KVM’s flexibility as a hypervisor, coupled with its open-source nature makes it a perfect choice for virtualization.
