The installing comprises creating each of the local files to the virtual disk with null data, wherein upon installation of the modified image, a plurality of disk blocks assigned to the local files contain a null indicator and do not contain any processable content. A streaming control module senses a request to access the virtual disk, determines whether streaming is indicated to satisfy the request, and transfers to the user system the processable content corresponding to the requested disk block. Streaming is indicated when the request corresponds to one of the disk blocks that does not contain any processable content. | 11-13-2008 |
20100122052 | Generating and Using Checkpoints in a Virtual Computer System - To generate a checkpoint for a virtual machine (VM), first, while the VM is still running, a copy-on-write (COW) disk file is created pointing to a parent disk file that the VM is using. Next, the VM is stopped, the VM' s memory is marked COW, the device state of the VM is saved to memory, the VM is switched to use the COW disk file, and the VM begins running again for substantially the remainder of the checkpoint generation. Next, the device state that was stored in memory and the unmodified VM memory pages are saved to a checkpoint file. Also, a copy may be made of the parent disk file for retention as part of the checkpoint, or the original parent disk file may be retained as part of the checkpoint. If a copy of the parent disk file was made, then the COW disk file may be committed to the original parent disk file. | 05-13-2010 |

20110066585 | EXTRACTING INFORMATION FROM UNSTRUCTURED DATA AND MAPPING THE INFORMATION TO A STRUCTURED SCHEMA USING THE NA VE BAYESIAN PROBABILITY MODEL - An “unstructured event parser” analyzes an event that is in unstructured form and generates an event that is in structured form. A mapping phase determines, for a given event token, possible fields of the structured event schema to which the token could be mapped and the probabilities that the token should be mapped to those fields. Particular tokens are then mapped to particular fields of the structured event schema. By using the Naïve Bayesian probability model, a “probabilistic mapper” determines, for a particular token and a particular field, the probability that that token maps to that field. The probabilistic mapper can also be used in a “regular expression creator” that generates a regex that matches an unstructured event and a “parameter file creator” that helps a user create a parameter file for use with a parameterized normalized event generator to generate a normalized event based on an unstructured event. | 03-17-2011 |
