Abstract
The present embodiments relate generally to master image management for a virtualization environment such as a virtual desktop infrastructure. Some embodiments are directed toward using image snapshot technology to identify differences between master images. In these and other embodiments, a methodology includes indexing the contents of snapshots of the same master image taken at different points in time to determine the delta between the snapshots, and thus the states of the master image at the different points in time.
Claims20
A method comprising:
- generating a second snapshot of an image, the image representing a configuration of a virtual machine associated with the image;
- generating a second index based upon a content of the second snapshot;
- and
- upon generating the second index, automatically comparing the second index with a first index generated from a first snapshot of the image captured before the second snapshot to identify a change in the configuration,
- wherein the virtual machine is installed on a server;
- wherein the first snapshot and the second snapshot are generated by a snapshot tool installed on the server;
- and
- wherein the first index and the second index are generated by an index tool installed on the server.

A method comprising:
- identifying a first snapshot and a second snapshot of a master image, the master image representing a configuration of a master virtual machine installed on a server, the first snapshot being generated by a snapshot tool installed on the server at a first point in time and the second snapshot being generated by the snapshot tool at a second point in time different from the first point in time;
- generating a first index based upon a content of the first snapshot, wherein the first index is generated by an index tool installed on the server;
- generating a second index based upon the content of the second snapshot, wherein the second index is generated by the index tool;
- and
- comparing the first index with the second index to identify a change in the configuration.

An apparatus comprising:
- a processor for executing programmed instructions to:
- create a snapshot of an image of a master virtual machine, the image representing a configuration of the master virtual machine;
- generate an index based upon a content of the snapshot;
- and
- automatically compare the index with another index created from a previously captured snapshot of the image to identify differences between the snapshot and the previously captured snapshot,
- wherein the snapshot and the index are generated on a server on which the master virtual machine is installed.
