Abstract
The disclosed embodiments provide a system that manages the use of a virtual disk. During operation, the system obtains trace data associated with a startup process that reads blocks from the virtual disk. Next, the system physically rearranges the blocks based on the trace data to increase the speed of the startup process. During execution of the startup process, the system also determines a progress of the startup process and uses the progress and the trace data to prefetch blocks from the virtual disk for use by the startup process.
