The invention relates to a method for placing a load-related virtual machine. In a currently common virtualized environment, in order to ensure performance, resources are often excessively allocated, leading to a low resource utilization level and resulting in increase of the cost and resource waste. By utilizing a multi-iteration complementary pairing method provided by the invention, the problems of a low resource utilization ratio as well as unreasonable pairing caused by random pairing or one-time pairing can be solved; and the iteration degree is controlled by setting a saturation of the resource utilization ratio, so that the performance of the system and the service quality of a user are controlled within an acceptable range. By a multi-iteration virtual machine method, by utilizing the time complementarity of the resources, the resource utilization ratio of the virtual machine can be improved in a relatively deep level on the premise of not reducing the service quality of the user.
