Embodiment Construction

[0024] According to an embodiment of the present invention, a method for storing an image file of a virtual machine is provided.

[0025] like figure 1 As shown, the storage method of the image file of the virtual machine according to the embodiment of the present invention includes:

[0026] Step S101, detecting the rate at which the virtual machine performs read and write operations;

[0027] Step S103, adjusting the storage where the image file of the virtual machine is located according to the detected rate and the read / write performance of multiple storages.

[0028] Wherein, each memory in the plurality of memories has a corresponding speed or a speed range, and when adjusting the memory where the image file of the virtual machine is located, the detected speed or the memory corresponding to the range where the speed is located is determined as The storage where the virtual machine's image file should be stored.

[0029] In one embodiment, the multiple memories includ...

Abstract

The invention discloses a storage method and device of mirror image documents of virtual machines. The storage method includes that the rate of reading and writing operation of the virtual machines is detected, and according to the detected rate and the reading and writing performance of a plurality of storers, the storer where the mirror image documents of the virtual machines are located is adjusted. The storer where the mirror image documents of the virtual machines are located is adjusted according to the rate of the reading and writing operation of the virtual machines and the reading and writing performance of the storers, so that different storers can play the maximum performance, and when the multiple virtual machines are virtualized on the basis of one physical machine, the requirement for intensively and randomly reading and writing small documents based on a virtualized platform can still be met, and the reading and writing performance of the storers can be ensured.

Description

technical field [0001] The present invention relates to the field of computers, and in particular, to a method and device for storing image files of a virtual machine. Background technique [0002] Now virtualization technology has increasingly become the mainstream of data centers. Central storage is the basis of various functions of virtualization. The existing storage technology was developed in the 1970s, and virtualization support has not been considered. It is not very suitable for virtualization storage. [0003] Now one physical machine can virtualize multiple virtual machines, and the stored disk IO will be several times that of the original situation. The random read and write capabilities of traditional SATA disks and SAS disks limit the development of virtualization, and new storage devices are required. To meet the situation of virtualization-intensive IO. [0004] The virtualization platform requires intensive random reading and writing of small files. Tradit...
