If Workload Balancing detects a performance issue while the pool is in Maximum Density mode, it attempts
to address the issue by recommending migrating workloads among the powered-on hosts. If Workload
Balancing cannot resolve the issue using this method, it attempts to power-on a host. (Workload Balancing
determines which host(s) to power-on by applying the same criteria it would if the optimization mode was
set to Maximum Performance.)
If, while migrating one or more virtual machines, Workload Balancing determines that increasing capacity
benefit the pool's overall performance, it turns hosts back on automatically or recommends doing so.
Important:
Workload Balancing never recommends powering on a host unless Workload Balancing powered it off.
Designing Environments for Power Management and VM Consolidation
When you are planning a XenServer implementation and you intend to configure automatic VM consolidation
and power management, consider your workload design. For example, you may want to:
•Place Different Types of Workloads in Separate Pools. If you have an environment with distinct types of
workloads (for example, user applications versus domain controllers or types of applications that perform
