ACCELERATING VIRTUAL MACHINE RESUME TIME USING A PRE-CACHED WORKING SET

摘要

A client transitions between a suspended virtual machine (VM) state and an active VM state by employing a working set comprising a VM state file and a working set index file. The VM state file serializes each of the VM components that is saved to storage. The working set index file contains indirect information that records the offset, length, and region of various pieces of the VM state and contains a VM working set. The VM suspend state serialization is implemented as either a monolithic or an incremental process.
