Embodiment Construction

[0117] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0118] refer to figure 1 , which shows a flow chart of the steps of Embodiment 1 of a data storage method for a virtual machine of the present application, which may specifically include the following steps:

[0119] Step 101, receiving the write request of the original data sent by the virtual machine in the host machine;

[0120] Generally speaking, virtual machine technology realizes virtualization by adding a layer of virtual machine monitor (Virtual Machine Monitor, VMM) on the physical device (also known as the host computer), such as virtualization processor, virtual memory manager (Memory Management Unit, MMU) and virtual I / O system, etc.

[0121] In the same physical device, multiple different...

Abstract

The embodiment of the present application provides a data storage method and device for a virtual machine. The method includes: receiving, in the host machine, a write request for original data sent by the virtual machine; detecting the request type of the write request; when the request type When it is the first write request, store the original data in the first storage device. The embodiment of the present application avoids direct persistence to the second storage device, greatly reduces storage I / O paths, reduces time and device resource consumption, and improves the write performance of distributed storage in a virtual machine environment.

Description

technical field [0001] The present application relates to the technical field of computer processing, and in particular to a data storage method for a virtual machine and a data storage device for a virtual machine. Background technique [0002] In cloud computing IaaS (Infrastructure as a Service, infrastructure as a service), cloud operators provide hosted physical machines, virtual machines and other facilities for different users to use according to their actual needs. [0003] Virtual Machine (Virtual Machine) service is one of the core services of IaaS. It refers to a system virtual machine, that is, a complete computer system that can be simulated, has complete hardware system functions, and runs in a completely isolated environment. [0004] In cloud computing, the I / O (input / output, input / output) requirements for storage services are relatively high, and in order to avoid user service interruption or data loss caused by hardware errors, a distributed file system is ...
