KVM for IBM z Systems™ provides flexible enterprise open source virtualisation to get the most performance from multiple Linux workloads.

Reduce costs utilising KVM open source virtualisation on both IBM z Systems and IBM LinuxONE platforms by running more workloads with fewer system deployments to improve service levels and meet demands with ease.

Meet KVM for IBM z Systems v1.1.2

This release of KVM for IBM z Systems supports several new capabilities that enhances KVM for IBM z Systems and IBM LinuxONE.

The benefits of open source virtualisation on KVM

Enterprise-level virtualisation

Improve performance, scalability and security with a cost effective alternative to proprietary x86 virtualisation.

Higher quality of service

Gain easy provisioning for predictability of delivery of service at high utilisation rate.

Ease of use and efficiency

Use the familiar Linux interface to gain greater operational efficiency for your virtualisation management.

The IBM team helped us get our data centre ready to house our first enterprise-class server. We are also part of IBM’s Beta Testing program for KVM, the open-source hypervisor, giving us early knowledge of KVM on the LinuxONE platform.

  • Reduce operating costs through x86 server consolidation and deployment of Linux workloads.
  • Simplify systems management through familiar interfaces to enable a single cross platform virtualisation.
  • Accelerate cloud deployments by seamlessly working with OpenStack.
  • Run your Linux workloads on the most trusted, scalable, available, and secure platforms – IBM z Systems and IBM LinuxONE.
  • Meet changing server demands with automatic provisioning of computing resources.
  • Gain high virtualisation and consolidation for price performance advantage, scalability on demand, security, and extreme consistent availability.

Features and benefits

  • Coexists with z/VM virtualisation environments, Linux on IBM z Systems, LinuxONE, z/OS, zVSE and zTPF.
  • Supports multiple type of workloads and is optimised for z Systems and LinuxONE architecture, multitenancy, and capacity on demand.
  • Integrates easily into existing cloud environments and accelerate cloud deployments by seamlessly working with OpenStack.
  • Uses standard virtualisation management tooling through OpenStack interfaces to increase operational efficiencies.
  • Enables higher-level virtualisation functions so that critical workloads receive resources and priority based on goals you establish.
  • Allows business applications to remain active while the workload is relocated for either load balancing or scheduled downtime.
  • Supports new analytic workloads with Single Instruction Multiple Data (SIMD) for competitive advantage.
  • Delivers higher compute capacity with support for Simultaneous Multithreading (SMT) to meet new business requirements.
  • RAS support enhanced for problem determination and high availability setup to reduce down time and quickly react to business needs.
  • Secures and protects business data with Crypto exploitation that leverages hardware acceleration for cryptographic functions.
  • Provides choices for flexibility based upon protocol environments.
  • Unattended installation of the KVM hypervisor simplifies administration.
  • Support for Canonical Ubuntu Linux distribution in addition to SUSE for KVM on IBM z Systems and IBM LinuxONE.
  • Boot Guest from Virtual CD/DVD simplifies the installation of guest operating system.
  • Guest CPU Hotplug dynamically add virtual CPUs (vCPUs) to a running guest.
  • IBM License Metric Tool Support (ILMT) enablement, which is a no-charge utility, that helps clients process value units licensing requirements.
  • Web Browser Based Installer is a new tool that simplifies the installation of the KVM hypervisor.
  • Text based installer enhancements broaden support for additional installation protocols enables dynamically adding DASD, and enhanced security by supporting encrypted page volumes.
  • Installer Enhancements broaden support for additional installation protocols enables dynamically adding DASD, and enhanced security by supporting encrypted page volumes.
  • User Interface for Guest Management virtual machine manager (virt-manger) provides users of x86 KVM the same tool to configure and manage virtual servers.
  • Support for Pacemaker and Corosynch ensures high availability of critical resources.
  • Kimchi Support provides a user management and system module management that provides an easy on-ramp for those who would like to start using KVM but are concerned they don’t have the experience.
