Read the z/VM brief
Abstract illustration of geometric shapes

IBM z/VM® is an operating system with security-rich and scalable hypervisor and virtualization technology designed to run guest servers such as Linux®, z/OS® and z/TPF virtual machines as well as Red Hat® OpenShift® on IBM Z® and LinuxONE servers.

IBM z/VM is designed to run hundreds to thousands of guest servers on a single IBM Z server or IBM LinuxONE server (where only Linux and z/VM guests are supported) with the highest degrees of efficiency and elasticity.

The ability of z/VM to support multiple machine images and architectures provides a highly flexible production and test environment for IBM Z and LinuxONE operating systems to:

  • simplify migration from one release to another.
  • facilitate the transition to newer applications.
  • provide a test environment whenever one is needed.
  • consolidate many systems onto one physical server.
Introducing z/VM 7.4

z/VM 7.4 is pre-announced, explore the features and functions.

z/VM continuous delivery updates

Benefits A fundamental strength of z/VM is the ability for virtual machines to share system resources with very high levels of resource utilization. z/VM provides extreme scalability, security and efficiency to create opportunities for cost savings, while providing a robust foundation for cognitive computing on the IBM Z and LinuxONE platforms. Foundation for cloud computing

Realize the benefits of on-premises cloud computing as part of hybrid cloud.

IT efficiency

Run up to thousands of Linux and container workloads for extreme scalability and efficiency.

Continuous operation

Help achieve continuous availability by integrating with IBM resiliency-focused offerings.

Single systems image

Share and coordinate resources within a single systems image to reduce planned outages and balance workloads across z/VM systems.
