A virtual machine management system may perform a three phase migration analysis to move virtual machines off of less efficient hosts to more efficient hosts. In many cases, the migration may allow inefficient host devices to be powered down and may reduce overall energy costs to a datacenter or other user. The migration analysis may involve performing a first consolidation, a load balancing, and a second consolidation when consolidating virtual machines and freeing host devices. The migration analysis may also involve performing a first load balancing, a consolidation, and a second load balancing when expanding capacity. |
