Identifying software responsible for a change in system stability

1. A computer program product including computer usable program code embodied on a tangible computer usable storage medium, the computer program product comprising:

computer usable program code for detecting an increase in an amount of instability in a first computer system;

computer usable program code for comparing a first set of software applications installed on the first computer system to each set of software applications installed on a plurality of other computer systems in communication with a management module;

computer usable program code for identifying a second computer system from among the plurality of other computer systems, wherein the set of software applications installed on the second computer system includes all of the first set of software applications except for a given software application; and

computer usable program code for identifying the given software application as the cause of the increase in the amount of instability in the first computer system.

2. The computer program product of claim 1 , wherein the first computer system and the plurality of other computer systems are virtual machines that share a common configuration profile.

3. The computer-implemented method of claim 1 , wherein the first computer system and the plurality of other computer systems are physical machines that share a common configuration profile.

4. The computer program product of claim 2 , further comprising:

computer usable program code for removing the identified software application from the first computer system.

5. The computer program product of claim 1 , wherein the first computer system and the plurality of other computer systems are managed by the same management module.

6. The computer program product of claim 5 , further comprising:

computer usable program code for the management module communicating with at least one other management module to share data identifying a set of software applications installed on each computer system, wherein each of the at least one other management module manages a plurality of computer systems.

7. The computer program product of claim 1 , wherein the first computer system and the plurality of other computer systems are virtual machines.

8. The computer program product of claim 1 , wherein the first computer system and the plurality of other computer systems are virtual machines cloned from the same virtual machine template.

9. A computer program product including computer usable program code embodied on a tangible computer usable storage medium, the computer program product comprising:

computer usable program code for detecting an increase in an amount of stability in a first computer system;

computer usable program code for comparing a first set of software applications installed on the first computer system to each set of software applications installed on a plurality of other computer systems in communication with a management module;

computer usable program code for identifying a second computer system from among the plurality of other computer systems, wherein the set of software applications installed on the second computer system includes all of the first set of software applications except for a given software application; and

computer usable program code for identifying the given software application as the cause of the increase in the amount of stability in the first computer system.

10. The computer program product of claim 9 , wherein the first computer system and the plurality of other computer systems are physical machines that share a common configuration profile.

11. The computer program product of claim 1 , wherein the identified software application is an update to a driver or firmware.

12. The computer program product of claim 1 , wherein the identified software application is an updated version of a previously installed software application.

13. The computer program product of claim 1 , wherein the identified software application includes a driver for a hard disk drive, a network interface, or an input/output port.

14. The computer program product of claim 1 , further comprising:

computer usable program code for installing an updated version of the identified software application to the first computer system, wherein the first computer system and the plurality of other computer systems are virtual machines.

15. The computer program product of claim 1 , further comprising:

computer usable program code for removing the identified software application from the first computer system.

16. The computer program product of claim 15 , wherein the first computer system and the plurality of other computer systems are virtual machines.

17. The computer program product of claim 15 , further comprising:

computer usable program code for removing the identified software application from at least one of the plurality of other computer systems.

18. The computer program product of claim 9 , wherein the first computer system and the plurality of other computer systems are virtual machines that share a common configuration profile.

19. The computer program product of claim 9 , further comprising:

computer usable program code for installing the identified software application to at least one of the plurality of other computer systems.

20. The computer program product of claim 9 , wherein the first computer system and the plurality of other computer systems are managed by the same management module.
