TLDR
In this article, the authors proposed a method, system and device for controlling a virtual machine (VM) which can shorten the time for starting the VM by combining the template image files and incremental image files.Abstract:
The invention discloses a method, system and device for controlling a virtual machine (VM), which can shorten the time for starting the VM. The method comprises the following steps: receiving a VM starting request from a user, wherein, the starting request comprises image file description information corresponding to the VM which is requested to be started; determining template image files and incremental image files corresponding to a VM operating system according to the image file description information; and further matching the image files locally saved by a physical machine for starting the VM with the determined template image files and incremental image files, and determining index image files for starting the VM according to a matching result and then loading the files. By utilizing the technical scheme, only the index image files need to be combined; and due to small occupied data quantity of the index image files, the combining operation can be completed within quite a short period of time so as to shorten the consumed time for starting the VM.read more
