Virtual machine deployment method

The invention discloses a virtual machine deployment method. The method includes the steps that servers capable of meeting the resource requirement amount of a current virtual machine vm to be deployed are selected from servers capable of deploying virtual machines and serve as candidate servers, wherein the resource requirement amount is the requirement amount of assembly resources relevant to server energy consumption; the matching degree Pq between the remaining resource amount of each candidate server and the resource requirement amount of the virtual machine vm is calculated, and the average energy consumption utilization rate Eq of each candidate server is calculated after the virtual machine is deployed on the candidate server; according to the matching degree Pq and the average energy consumption utilization rate Eq, the comprehensive adaption degree Gp of each candidate server is calculated; the candidate server with the highest comprehensive adaption degree Gp is selected from the candidate servers and serves as the server for deploying the virtual machine vm. Through the method, the resource utilization rate of the servers can be effectively increased, and overall energy consumption in a data center is reduced.
