Abstract
A technique for data de-duplication is applied to suspend and resume operations for virtual machines (VMs) to reduce the time needed to suspend or resume a virtual machine and store the suspended VMs in a space-efficient and time-efficient manner. A VM's state is serialized and written to disk in the form of key values that are used to retrieve data from a key-data map. The key-data map stores unique data blocks for suspended VM images. The key-data map can be stored in a solid-state drive to further reduce latency and access time.
