What is z/VM?

IBM® z/VM® is a highly secure and scalable virtualization technology for cloud infrastructure and for running critical applications on IBM Z® and LinuxONE™ servers. The IBM z/VM Continuous Delivery model enables clients to exploit new and innovative z/VM capabilities at their own pace.

IBM z/VM supports multiple operating systems: Linux, z/OS®, z/VSE® and z/TPF on IBM Z and LinuxONE servers and can host thousands of virtual servers on a single IBM z15™ enterprise platform.
