To address the issue of scheduling mixed-workloads in resource virtualization environments,a novel virtual machine scheduling algorithm based on energy-consumption ratio model is proposed. In the proposed algorithm,the recent energy consumption status of individual virtual machines are evaluated by using the processor 's ‘performance monitor counters' mechanism,and the scheduling policy is‘most recent minimal energy-consumption ratio first'. Theoretical analysis presents the validation and characteristics of the proposed algorithm. Extensive experiments showthat when the system is in presence of intensive mixed-workloads,the proposed algorithm significantly outperforms existing scheduling approaches in terms of scheduling deviation and normalized energy-efficiency.
