vSphere DRS recommendation output: Cluster: Production Current load imbalance: 30% Recommended migrations: 1. Move VM 'Web01' from host01 (CPU usage 85%) to host04 (CPU usage 30%) Benefit: Improve balance by 10% 2. Move VM 'DB01' from host03 (CPU usage 90%) to host04 (CPU usage 30%) Benefit: Improve balance by 15% Note: host04 is in power-on state and has sufficient resources.
