IBM z/VM is a hypervisor operating system used on IBM’s mainframe computers. It allows multiple virtual machines (VMs) to run on a single physical server, each with its own operating system and resources, enabling efficient resource management and isolation. z/VM is designed for high availability, security, and scalability in enterprise environments.
