Curing CPU constraints by offloading guests with high CPU load

In this scenario how the CPU pressure generated by several Linux™ guest systems working in parallel on the source host system can be alleviated by relocating the Linux guest with the highest CPU load (the transactional database workload) is investigated.

For this analysis, the mixed workload environment was used (see Mixed workload); particularly, each LPAR for the z/VM hosts was configured with 34 GiB of real storage and with four CPs (see Figure 1).
