5.4. Load Balancing Policy: Evenly_Distributed

Figure 5.1. Evenly Distributed Scheduling Policy
An evenly distributed load balancing policy selects the host for a new virtual machine according to lowest CPU load or highest available memory. The maximum CPU load and minimum available memory that is allowed for hosts in a cluster for a set amount of time are defined by the evenly distributed scheduling policy's parameters. Beyond these limits the environment's performance will degrade. The evenly distributed policy allows an administrator to set these levels for running virtual machines. If a host has reached the defined maximum CPU load or minimum available memory and the host stays there for more than the set time, virtual machines on that host are migrated one by one to the host in the cluster that has the lowest CPU or highest available memory depending on which parameter is being utilized. Host resources are checked once per minute, and one virtual machine is migrated at a time until the host CPU load is below the defined limit or the host available memory is above the defined limit.

Where did the comment section go?
Red Hat's documentation publication system recently went through an upgrade to enable speedier, more mobile-friendly content. We decided to re-evaluate our commenting platform to ensure that it meets your expectations and serves as an optimal feedback mechanism.
