APPARATUS AND METHOD FOR PROVIDING VIRTUAL MACHINE IMAGE FILE

摘要

Provided is a method of providing a virtual machine image file in a cloud computing-based virtual desktop infrastructure. This method includes moving a golden image, an initial image provided from a shared storage, to a virtual machine driving server, converting the golden image into an image of a copy-on-write file format, and storing the same in a cache; allocating the converted virtual machine image to a virtual machine, and storing images of each virtual machine in the shared storage and managing the same to recover a virtual desktop when a disaster occurs. The method includes generating only data changed by the virtual machine, as a virtual machine image file, and managing the same, and hierarchically configuring a virtual machine image file based on a base image and storing the same in a cache memory in order to increase a loading rate of the virtual machine image file including the base image-based virtual machine image file.
