Objectives
The tests used in this project aim to evaluate the impact of live guest relocations in workloads running under the different environments.
The objectives of this project are:
- Evaluation of the impact of z/VM® live guest relocation on workloads running under Linux™ for System z® in the relocated z/VM virtual machine
- Evaluation of the characteristics of such workloads on the live guest relocation process
- Evaluation of the impact of the load situation in the source z/VM host system on the live guest relocation process
- Evaluation of the impact of the guest size on the live guest relocation process
- The resulting performance of the live guest relocation process
is evaluated through parameters such as:
- The relocation time and quiesce times
- The amount of memory transferred during the relocation process
