Abstract
A scheduling method for virtual processors based on the affinity of NUMA high-performance network buffer resources, including: in a NUMA architecture, when a network interface card (NIC) of a virtual machine is started, getting distribution of the buffer of the NIC on each NUMA node; getting affinities of each NUMA node for the buffer of the network interface card on the basis of an affinity relationship between each NUMA node; determining a target NUMA node in combination with the distribution of the buffer of the NIC on each NUMA node and NUMA node affinities for the buffer of the NIC; scheduling the virtual processor to the CPU on the target NUMA node. The problem of affinity between the VCPU of the virtual machine and the buffer of the NIC not being optimal in the NUMA architecture is solved to reduce the speed of VCPU processing network packets.
