Abstract

The invention discloses a data file storage method and apparatus for a virtual machine, and the KVM (K Virtual Machine). The method comprises the steps of creating a mounting point in a memory according to a received memory mounting point creation command; and according to a received storage position instruction, setting a data file storage position of the VM corresponding to the storage position instruction as the mounting point. The mounting point is created in the memory according to the received memory mounting point creation command, so that a storage space used for storing data files can be created in a memory; the data file storage position of the VM corresponding to the storage position instruction is set as the mounting point, so that the data files of the VM corresponding to the storage position instruction can be stored in the storage space of the memory according to a user demand; and therefore, the IO performance of the VM is remarkably improved, the IO bottleneck problem is solved, the overall performance of the VM is improved, and the experience of a user to virtualized environment applications is improved.

Description

technical field [0001] The invention relates to the field of virtual machines, in particular to a method and device for storing data files of a virtual machine and a KVM virtual machine. Background technique [0002] With the development of cloud computing, more and more IT applications are now deployed on cloud platforms based on virtual machines. Therefore, the performance of virtual machines often determines the performance of IT applications. Today, with excess processor and memory performance, computing power is no longer the bottleneck of virtual machines. However, as IO devices are low-speed devices, the problem of IO bottlenecks has become more and more serious. Therefore, how to improve the IO performance of the virtual machine, and then improve the performance of the virtual machine and optimize the performance of the cloud platform is a hot issue today. [0003] In the prior art, the IO performance of the virtual machine is often improved by replacing the hardwar...
