An illustrative embodiment disclosed herein is a host device including a plurality of virtual machines and a controller virtual machine configured to compute a plurality of central processing unit (CPU) usages corresponding to the plurality of virtual machines. The controller virtual machine is further configured to compute a total usage as a sum of the plurality of CPU usages and to flag one or more outlier virtual machines of the plurality of virtual machines responsive to one or more exceeding CPU usages of the one or more outlier virtual machines being greater than a threshold usage. The controller virtual machine is further configured to assign weights to the one or more outlier virtual machines and to select, for virtual machine migration, a first outlier virtual machine of the one or more outlier virtual machines responsive to the total usage being greater than a target usage.
