Problems solved by technology

For example, physical hard disk resources are shared among multiple virtual machines by dividing the physical hard disk space. However, the ability of physical hard disks to process input and output commands is limited. If resources are seized between virtual machines, when processing input and output commands, the There is an uneven distribution of resources, which will cause some user-side input and output commands to be unprocessed for a long time

Embodiment Construction

[0020] The embodiment of the present invention provides a method for processing input and output instructions, which can control and process the input and output instructions on different virtual machines, so that the physical resources occupied by each virtual machine are pre-divided, avoiding virtual machine The input and output instructions of the user terminal brought about by preempting physical resources between them cannot be processed for a long time. Each will be described in detail below.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of ...

Abstract

The present invention discloses an input and output instruction processing method. The method comprises: obtaining an identifier of a virtual machine that input and output instructions, which request access to the virtual machine, request access to; making statistics on the capacity of the input and output instructions performed in unit time on the identified virtual machine; and according to the relationship between the capacity and a pre-divided capacity of the identified virtual machine, processing the input and output instructions requesting access to the virtual machine. According to the input and output instruction processing method, the input and output instructions on different virtual machines can be controlled and processed, so that physical resources occupied by each virtual machine are occupied according to predetermined division, and the problems of unequal distribution of user-side resources and incapability of processing certain input and output instructions in a long time as the virtual machines seize the physical resources mutually are avoided.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for processing input and output instructions. Background technique [0002] Virtualization technology is to run multiple operating systems on a physical machine at the same time, and these operating systems cannot perceive each other. In essence, virtualization technology abstracts a single resource on a physical machine into multiple resources through space division, time-sharing and simulation. [0003] A virtual machine is an independent computer system provided by a virtualization technology, and each virtual machine has its own virtual hardware, such as a central processing unit (Central Processing Unit, CPU), memory, and input / output (Input / Output, IO) devices. After using virtualization technology, a physical machine can be virtualized into multiple virtual machines. [0004] Because there is only one copy of physical resources, physical machines fa...
