Abstract

The disclosure is directed to automatic virtualization based on user-defined criteria. In one example, data representative of user-defined criteria is received, a virtualization heuristic is generated based on the user-defined criteria, the virtualization heuristic is activated, an occurrence of an event defined by the user-defined criteria is detected, and at least one virtualization operation is automatically performed in response to the detected event. In certain embodiments, the virtualization operation is selected based on the user-defined criteria. In certain embodiments, the virtualization operation includes capturing file system and configuration activity associated with the detected event and storing data representative of the captured file system and configuration activity to a virtual layer.

Claims

1. A method, comprising:

receiving data representative of user-defined criteria, the user-defined criteria defining an event that triggers initiation of at least one virtualization operation;

utilizing the user-defined criteria to generate a virtualization heuristic that includes a set of one or more rules for controlling the at least one virtualization operation;

implementing the virtualization heuristic within a virtualization engine configured to use the virtualization heuristic to monitor, at an operating system kernel level, for the event defined by the user-defined criteria and to automatically control the at least one virtualization operation;

detecting, by the virtualization engine, an occurrence of the event defined by the user-defined criteria, wherein detection of the occurrence of the event triggers initiation of the at least one virtualization operation; and

automatically performing the at least one virtualization operation in response to the detected event, including;

capturing file system and configuration activity associated with the detected event, the file system and configuration activity being associated with a base operating system, and

storing data representative of the captured file system and configuration activity to a virtual layer without changing a base file system and configuration of the base operating system, wherein, when the virtual layer is enabled, access requests associated with the captured file system and configuration activity are redirected from the base file system and configuration to the virtual layer.

2. The method of claim 1, wherein:

the event defined by the user-defined criteria comprises initiation of a software installation process;

the virtualization engine detects the event by monitoring for and detecting initiation of the software installation process.

3. The method of claim 2, wherein

the user-defined criteria comprises a process identifier that identifies a particular process associated with software installation.

4. The method of claim 2, wherein:

the user-defined criteria comprises data descriptive of a particular type of process;

the particular type of process comprises the software installation process.

5. The method of claim 2, wherein the

virtualization engine monitors for and detects initiation of the software installation process by monitoring for and detecting a call to the software installation process.

6. The method of claim 1, wherein the user-defined criteria include at least one of a file identifier, a file type identifier, a file extension identifier, and a file location identifier.

7. The method of claim 1, wherein the event comprises an initiation of an installation of a software application, and wherein the at least one virtualization operation includes virtually installing the software application to the virtual layer in lieu of actually installing the software application to the base operating system.

8. The method of claim 7, further comprising enabling the virtual layer to activate the software application.

9. The method of claim 1, wherein the virtualization engine comprises a filter driver that is implemented at the operating system kernel level and performs the monitoring for the event.

10. A computer program product embodied in a non-transitory computer readable medium and comprising computer instructions executable by a computing device to perform the functions of:

receiving data representative of user-defined criteria, the user-defined criteria defining an event that triggers initiation of at least one virtualization operation;

utilizing the user-defined criteria to generate a virtualization heuristic that includes a set of one or more rules for controlling the at least one virtualization operation;

implementing the virtualization heuristic within a virtualization engine configured to use the virtualization heuristic to monitor, at an operating system kernel level, for the event defined by the user-defined criteria and to automatically control the at least one virtualization operation; and

automatically selecting and performing the at least one virtualization operation in response to the event, the at least one virtualization operation being selected based on the user-defined criteria, wherein the at least one virtualization operation stores data to a virtual layer without changing a base file system and configuration of a base operating system and, when the virtual layer is enabled, access requests associated with the data stored to the virtual layer are redirected from the base file system and configuration to the virtual layer;

wherein the at least one virtualization operation includes;

capturing file system and configuration activity associated with the event, and

storing data representative of the captured file system and configuration activity to the virtual layer.

11. The computer program product of claim 10, wherein the captured file system and configuration activity is selectively identified based on the user-defined criteria.

12. The computer program product of claim 10, wherein the user-defined criteria include at least one of a process identifier, a process type identifier, a file identifier, a file type identifier, a file extension identifier, a file location identifier, and schedule data.

13. The computer program product of claim 10, wherein the event comprises an initiation of an installation of a software application, and wherein the at least one virtualization operation includes virtually installing the software application in lieu of actually installing the software application to the base operating system.

14. The computer program product of claim 10, wherein the user-defined criteria define at least one user type that identifies whether a user is privileged, and wherein the at least one virtualization operation is selected based at least in part on the user type.

15. The computer program product of claim 14, wherein the at least one user type comprises a non-privileged user.

16. A system, comprising:

a software management subsystem running on a base operating system;

a computing device communicatively coupled to the software management subsystem;

a criteria manager implemented in at least one of the software management subsystem and the computing device, the criteria manager being configured to;

receive data representative of user-defined criteria, the user-defined criteria defining an event that triggers initiation of at least one virtualization operation, and

utilizing the user-defined criteria to generate a virtualization heuristic that includes a set of one or more rules for controlling the at least one virtualization operation; and

a virtualization engine implemented in the computing device and configured to communicate with the criteria manager, the virtualization engine being configured to implement and utilize the virtualization heuristic to monitor for and detect an occurrence of the event at an operating system kernel level, and

automatically perform the at least one virtualization operation in response to the detected event, wherein the at least one virtualization operation stores data to a virtual layer without changing a base file system and configuration of the base operating system and, when the virtual layer is enabled, access requests associated with the data stored to the virtual layer are redirected from the base file system and configuration to the virtual layer;

wherein the at least one virtualization operation includes;

creating the virtual layer,

selectively capturing file system and configuration activity associated with the detected event, and

storing data representative of the captured file system and configuration activity to the virtual layer.

17. The system of claim 16, wherein the virtualization engine is configured to select the at least one virtualization operation based on the user-defined criteria.

18. The system of claim 16, wherein the criteria manager is configured to provide at least one tool enabling a user of the software management subsystem to define the user-defined criteria, and wherein the software management subsystem is configured to transmit data representative of the user-defined criteria to the computing device for use by the virtualization engine.
