Fine-grained resource dispatching system and fine-grained resource dispatching method based on virtualization platform

The invention relates to a fine-grained resource dispatching system based on a virtualization platform. The fine-grained resource dispatching system comprises a load information obtaining unit, a matrix generating unit, a matrix analysis unit, a load fluctuation judging unit, a load dispatching value regulating unit and a resource allocation unit. The fine-grained resource dispatching system has the advantages that by collecting the load values of each virtual machine in server nodes, a resource dispatching analysis model is designed; the deserved resource quantity of each virtual machine is decided; and under the condition that the resource allocation does not conform to requirements, a fine-grained resource dispatching mode is called for dynamically increasing and decreasing resources for the virtual machines. The invention also provides a fine-grained resource dispatching method based on the virtualization platform.
