Abstract: A computer implemented method, apparatus, and computer usable code for managing versioning data for objects in a virtual machine. A request to allocate an object is received, wherein the request identifies a plurality of parameters for classifying the object. An entry for the object is created in a versioning data structure using the plurality of parameters received in the request. The versioning data structure is used to store delta data for change in the data for the object and wherein the object is associated with the data structure. When a change in the data for the object occurs, the delta data is stored in the versioning data structure based on the plurality of parameters. A particular version of the object may be retrieved using the plurality of parameters.
