Summary:The invention discloses an NUMA node binding configuration method and device for multiple virtual machines, and the method comprises the steps: obtaining the distance information of each NUMA node on a host for accessing the own memory and accessing the memories of other nodes, and obtaining the distance between the NUMA nodes; combining the NUMA nodes according to the distance between the NUMA nodes to form a plurality of node combinations; and performing NUMA node binding according to the scheduling priority required to be configured by each to-be-configured virtual machine, binding each to-be-configured virtual machine required to be configured with the highest scheduling priority to a corresponding single NUMA node, and binding part or all of the rest of the to-be-configured virtual machines to each NUMA node in the corresponding node combination. The method has the advantages of being simple in implementation method, low in cost, capable of achieving load balancing, small in expenditure, high in resource
