Abstract

The subject technology addresses the need in the art for improving intra-cloud migration of virtual machines in a cloud computing environment. A hash database may be prepopulated with key-value pairs corresponding to hash IDs and associated data chunks of a virtual machine image. In this regard, the virtual machine image may be divided into chunks using boundaries chosen by a Rabin fingerprinting technique. A hash (e.g., MD5 or SHA-1) may be computed over each chunk and act as a unique identifier for the data contained in each chunk. At appropriate times, one or more hash IDs are sent instead of the actual data chunks between clouds when performing the inter-cloud migration of a virtual machine.
