Binding method and device for virtual CPU core and physical CPU core, equipment and storage medium

Abstract

The invention discloses a binding method and device for a virtual CPU core and a physical CPU core of a cloud host, equipment and a storage medium. In the present application, the method comprises thefollowing steps of: dividing a special physical CPU resource pool which only performs virtual CPU core binding from physical CPU resources of a server so as to receive the binding request. The virtual CPU core can be bound with the physical CPU core in the special physical CPU resource pool. When an allocation request of the physical CPU core is received, . bound physical CPUs can be distributedfrom other resource pools, so that the bound physical CPUs can be prevented from influencing the distribution of the physical CPUs, an effective physical CPU resource management mode is provided, theperformance of the cloud host is improved, and the high availability and utilization rate of the physical resources of the cloud platform are improved.

Description

technical field [0001] The present invention relates to the technical field of resource management, and more specifically, to a binding method, device, equipment, and computer-readable storage medium for a virtual CPU core and a physical CPU core of a cloud host. Background technique [0002] Cloud host is an important part of cloud computing in infrastructure applications. It is located at the bottom of the pyramid of the cloud computing industry chain and originates from the cloud computing platform. At present, when creating a cloud host, it is necessary to bind the virtual CPU (central processing unit, central processing unit) core of the cloud host to the physical CPU core, but when binding the physical CPU core, it can only be randomly selected in the resource pool for binding , the physical CPU core cannot be specified, which will cause the physical CPU core to not be fully utilized, for example: [0003] Assuming that there are 0-6 cores on NUMA node0 of server A, a...

Problems solved by technology

At this time, if a request is made to create a 4-core cloud host b, then NUMA node0 will be excluded and considered not to meet the conditions for creating a cloud host

However, the number of physical CPU cores meets the creation conditions. It is only because cloud host a occupies 4 physical cores, causing other cores to be dispersed, so it cannot meet the request conditions of cloud host b, resulting in waste of physical CPU resources.
