Abstract
A method and system for tracking a virtual machine is provided. The method includes determining updates applied to virtual machine instances and tracking updates associated with a master image used to generate the virtual machine instances. High level semantic updates to the master image are identified by performing a breadth-first search on a version graph to identify a cut on the version graph such that each edge in the cut comprises all elements of the high level semantic updates and splitting a node that immediately follows the cut into a node Vand a node VThe node Vcaptures changes of the high level semantic updates and the node Vcaptures changes not in the high level semantic updates. The node Vis promoted to a root. A version tree configured to track drift of each virtual machine instance with respect to the master image is maintained.
