nodes, resulting in all containers being created on the same node. Similar to nova, it is mainly to increase the weight calculation of the scheduling strategy, which is very necessary. The impact on zun\u0027s overall scheduling process is relatively small. After node filtering, add node weight calculation method, so that zun\u0027s scheduling tasks can be distributed to different nodes, making the scheduling strategy more healthy.\n\nFor the current version, the node hardware configuration of our environment:\n```\ncomputer01\t16H64G7T\tzun-compute\ncomputer02\t16H64G7T\tzun-compute\ncomputer03\t16H64G40T\tnova-compute\ncomputer04\t16H64G7T\tnova-compute\ncontroller01\t16H64G40T\tcontroller\n\n```\nThe \"scheduler\" config of \"zun.conf\" is:\n```\n[scheduler]\n# * A string, where the string corresponds to the class name of a scheduler\n#   driver.
