6.4. Power Management Configuration

6.4.1. Power management configuration

Configure Power Management
At this point, you should have two hosts and at least two virtual machines, however this lab uses six virtual machines. You can use as many virtual machines as you want, but for optimal demonstration of high availability features, it is recommended that you add four new virtual machines to your environment.
Highly available virtual machine settings will only be effective if power management is enabled on the hosts. However before configuring power management, recall that you have previously defined a power saving cluster policy. Cluster policies and high availability can be used concurrently; however to best demonstrate Red Hat Enterprise Virtualization's high availability features for this lab, reset the cluster policy. This ensures that the virtual machines remain where they are staged before each demonstration, so the migration is triggered by high availability rather than the cluster's load balancing policies.
