Hi, try checking if load balancing is set on the failover cluster itself. try using the highest mode.
(Get-Cluster).AutoBalancerMode = <value> Windows Admin Center can enable the load-balancing recommendation feature, but it does not actively redistribute VMs by itself. It only exposes the cluster’s built-in Load Balancer for VM placement recommendations.
If VMs are not moving, check:
- Whether the cluster has Dynamic Optimization enabled (Failover Cluster Manager or PowerShell). WAC only toggles the flag but does not trigger movement.
• Whether the cluster nodes show balanced CPU and memory usage. If the cluster does not detect imbalance, no movement happens.
• Whether the cluster is in maintenance mode or has constraints such as anti-affinity rules.
• Whether live migration is allowed between all nodes.
Start troubleshooting from Failover Cluster Manager or by running cluster validation. WAC is only a management surface; the actual balancing logic depends on the cluster configuration.
