外文摘要：The modern university computer lab and kindergarden through 12th grade classrooms require a cen-tralized solution to efficiently manage a large number of desktops.The existing solutions either bring virtualization overhead in runtime or requires loading a large image over 30 GB leading to an unacceptable network latency.In this work,we propose Troy which takes advantage of the differencing virtual hard disk techniques in Windows systems.As such,Troy only loads the modifications made on one machine to all other machines.Troy consists of two mod-ules that are responsible to generate an initial image and merge a differencing image with its parent image,respec-tively.Specifically,we identify the key fields in the virtual hard disk image that links the differencing image and the parent image and find the modified blocks in the differencing images that should be used to replace the blocks in the parent image.We further design a lazy copy solution to reduce the I/O burden in image merging.We have imple-mented Troy on bare metal machines.The evaluation results show that the performance of Troy is comparable to the native implementation in Windows,without requiring the Windows environment.
