The data stream processing method and apparatus for multi-cpu virtual machine system

The present invention discloses a method and apparatus for processing a data stream a multi-CPU virtual machine system, the method comprising: determining a virtual machine to forward its own CPU utilization rate of the CPU, and determines the operating state of the CPU itself forward; if the overload status does not currently exist forwarding CPU, and the current state of the at least two low-load forwarding CPU, the virtual machine selected from the forwarding CPU in a low-load state to be transferred out of the data streams and forwards the CPU into the data stream to be forwarded CPU; the indicative of said virtual machine to be transferred out of the CPU data stream forwarding the data stream transfer, freeing the CPU to be transferred out of the data stream forwarding CPU, and instructing the CPU to be forwarded into the data stream into the data stream . Embodiment of the present invention, the rational use of CPU resources, to avoid wasting CPU resources, to enhance the utilization efficiency of CPU resources.
