VM Resource Manager (VMRM)
Updated: 15 July 2008
VMRM provides functions to dynamically tune the z/VM system. Groups of virtual machines can be defined to be part of a workload. The workloads can then be managed by VMRM to goals that are also defined. The system administrator can use VMRM to create a form of group scheduling for a set of virtual machines. There can be multiple workloads (groups of virtual machines), each managed to different goals. VMRM automatically adjusts performance parameters when there is contention between virtual machines for a resource. Therefore, VMRM is not effective in environments where resources are unconstrained.
Read more about VMRM in Chapter 17 of the z/VM: Performance publication.
