Abstract

The embodiment of the invention provides a data loading method and device, and relates to the field of computers. The method comprises the steps of obtaining a writing request of a virtual machine after the virtual machine is started, wherein the writing request is used for writing virtual machine data generated by the virtual machine to a target position in a volume of the virtual machine; when the attribute of the volume is a delay loading attribute, obtaining the loading state of the target position from a bit table volume, wherein the bit table volume is created when a blank volume is created and is used for indicating loading states of data on all positions in the volume, the loading states comprise not loaded, loading and loaded, and loading is used for indicating loading of data onthe corresponding position from a mirror file; when the loading state of the target position is loading, pausing responding of the writing request till the loading state of the target position is loaded and writing the virtual machine data into the target position in the volume. The data loading method and device solve the problem of data conflicts in the data loading process, and the accuracy ofthe data loaded by the virtual machine is improved.

Description

technical field

[0001] The present application relates to the computer field, in particular to a data loading method and device. Background technique

[0002] Virtualization technology is an important technology in cloud computing system, through which the capacity of hardware can be expanded and the process of reconfiguring software can be simplified. Virtualization of the central processing unit (Central Processing Unit, CPU), memory, network, etc. through virtualization technology can allow multiple virtual machines to run simultaneously in a cloud computing system, and each virtual machine can run independently without mutual interaction. influences. In addition, in order to improve the efficiency of creating a virtual machine, the cloud computing system will save the image file, which is the CD image file needed to create a virtual machine, and a new virtual machine can be created by copying the image file.

[0003] A cloud computing system usually includes the follow...
