Abstract

A method and device for pulling a virtual machine mirror file includes: obtaining a mirror pulling instruction comprising a timestamp of a mirror file; determining whether the mirror pulling instruction instructs only a base mirror file; if yes, obtaining locally the base mirror file previously dispatched to physical machines; and if not, obtaining locally the base mirror file previously dispatched to physical machines, and obtaining an incremental file matching the timestamp of the mirror file. The amount of data of the virtual machine mirror file to be pulled by the virtual machine mirror management module is reduced by using the base mirror file previously dispatched to physical machines, such that the pulling period is shortened, and the loads of a server where the virtual machine mirror management module is located and the loads of the mirror server are decreased. Accordingly, the creation of the virtual machine may be accelerated.
