Virtual processor scheduling method based on NUMA high-performance network processor loads

The invention discloses a virtual processor scheduling method based on Non-Uniform Memory Access Architecture (NUMA) high-performance network processor loads. The method comprises the steps that when a virtual machine starts a virtual function network card distributed by a Single-Root I/O Virtualization (SR-IOV) high-performance network card, the affinity situation of a virtual machine network card buffer and an NUMA node is obtained by monitoring the running of the virtual machine network card; then, the VCPU running load situation is obtained for the VM and a DOM0, and the PCPU running loads on the NUMA node are obtained through the mapping relation between the VCPU and the PCPU; finally, according to the affinity of the NUMA node and the buffer and real-time load information of a processor of the NUMA node, the final scheduling result is obtained. The VCPU processing network data packets can have the advantages of the affinity and processor resources, and therefore the network performance of a high-performance network server under the virtualization environment can be obviously improved.
