Real-time virtual machine memory scheduling method and device

Abstract

The invention discloses a real-time virtual machine memory scheduling method and device. The memory scheduling method comprises the steps that when the memory resource of a mainframe exceeds the preset threshold value, the memory resource of the mainframe is determined to be in a stressed state; when the memory resource of the mainframe is in a stressed state, the memory usage rate of a virtual machine is queried; the spatial memory punishment coefficient is introduced, the size of the released memory is calculated; the memory of the virtual machine is reallocated according to the calculated size of the released memory. According to the memory scheduling method, the optimization of memory allocation is achieved, and wastes of memory resources are avoided.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a real-time virtual machine memory scheduling method and device. Background technique [0002] At present, virtualization is the key technology of the underlying infrastructure of cloud computing. Through the virtualization of hardware resources, storage, network and operating system, the entire cloud computing environment can be integrated into a resource pool, so that the server application level has Plasticity and controllability, which greatly reduces the cost of server deployment, management and heat dissipation, and realizes energy saving, automation, virtualization, service integration and business continuity. In the virtualization technology, the virtualization of computing resources is one of its key components. Since the performance of a computer system is limited by the slowest component in the system, the resource configuration of a computer determines the per...

Problems solved by technology

However, there are certain problems in the above two methods, that is, the memory can only be pre-set before the memory resource shortage occurs, rather than real-time scheduling, so that the host cannot well balance the memory resources in the case of memory resource shortage. The allocation of memory between machines has caused a certain degree of waste of memory resources.
