Abstract

See full text

A computer-implemented method for defragmenting virtual machine prefetch data. The method may include obtaining prefetch information associated with prefetch data of a virtual machine. The method may also include defragmenting, based on the prefetch information, the prefetch data on physical storage. The prefetch information may include a starting location and length of the prefetch data on a virtual disk. The prefetch information may include a geometry specification of the virtual disk. Defragmenting on physical storage may include placing the prefetch data contiguously on physical storage, placing the prefetch data in a fast-access segment of physical storage, and/or ordering the prefetch data according to the order in which it is accessed at system or application startup.
