Method and device for improving calculating ability of virtual machine in resource monopolizing and exclusive mode

Abstract

The invention discloses a method and device for improving calculating ability of a virtual machine in a resource monopolizing and exclusive mode. The method comprises the steps that firstly, a task is issued through a task issuing system, and whether the virtual machine needs high-performance calculating ability is described in the task; secondly, after a task executing system receives virtual machine building information, a virtual machine building module is called, and the virtual machine is built according to front-end input data; thirdly, after the virtual machine is built, according to requirements, if an appointed CPU needs to be monopolized, a new request for calling a CPU binding module is generated, and binding of a virtual machine VCPU is completed through the CPU binding module. By means of the method and device, in some specific scenes, for example, an oracle data base operates in the virtual machine, IO and concurrence ability of the virtual machine needs to be guaranteed. According to the method and device, by changing a CPU processing mode, the processing ability of the virtual machine can be improved.

Description

technical field [0001] The present invention relates to technical fields such as virtualization, operating system, and kernel scheduling, and in particular to a method and device for improving the computing capability of a virtual machine with exclusive and exclusive resources. Background technique [0002] Virtualization technology is a technology that virtualizes physical resources and provides them to users. Due to the huge benefits it can bring, it is attracting attention from all over the world. Virtualization refers to computing elements operating on a virtual basis rather than a real basis. Virtualization technology can expand the capacity of hardware and simplify the process of reconfiguring software. CPU virtualization technology can simulate a single CPU into multiple CPUs in parallel, allowing one platform to run multiple operating systems at the same time, and applications can run in independent spaces without affecting each other, thereby significantly improvin...

Problems solved by technology

[0004] It can be seen that since CPU resources are not independently occupied, it may be affected by the load level of other clients in the host computer, affecting the overall processing capacity of the client computer.

[0005] In addition, because the CPU will communicate with each hardware, when a hardware sends an interrupt request, the CPU will suspend the current task to process the interrupt request. If the interrupt request is processed frequently, its processing capacity will also be reduced.
