Abstract

A method, apparatus and system for transparently unifying virtual machines (“VMs”) is disclosed. An embodiment of the present invention enables a user to interact with various applications on a VM host while unaware of the VM structure on the VM host. The user may be presented with a unified desktop interface representing a composite and/or unified view of the VM host. Via this unified desktop interface, the user may perform all necessary commands and/or receive output. Invisible to the user, the unified desktop interface represents a unification console. The unification console may be an independent component (e.g., an enhanced VM) and/or a subset of a virtual machine manager (“VMM”) component on the VM host. In either situation, the unification console may, alone and/or in conjunction with the VMM, route and/or redirect and/or transform and/or filter the user'"'"'s commands to the appropriate applications and redirect and/or copy and/or transform and/or filter the output from the applications to be displayed in the unified desktop interface.

Claims

1. A method for transparently unifying virtual machines (“

VMs”

) on a host computer, comprising;

accepting user input into a unified desktop interface representing an interface for a unification console, the unified desktop interface including a graphical user interface to present a composite view of applications residing within the VMs on the host by displaying a plurality of application icons of application residing in a plurality of virtual machines;

identifying an application corresponding to the input;

identifying a VM in which the application resides;

sending the input to the application, wherein sending the input to the application further comprises one of filtering and transforming the input;

and causing output from the application to be redirected to the unification console, wherein causing the output from the application to be redirected to the unification console further comprises one of filtering and transforming the output.

2. The method according to claim 1 further comprising presenting the output from the application on the unified desktop interface.

3. The method according to claim 1 further comprising:

determining whether the application is currently executing in the VM in which the application resides; and

if not, causing the application to begin executing.

4. The method according to claim 1 wherein the unification console identifies at least one of the application and the VM in conjunction with a virtual machine manager (“

VMM”

).

5. The method according to claim 1 wherein the unification console is executing in a VM.

6. The method according to claim 1 wherein the unification console is included in a virtual machine manager.

7. The method according to claim 1 wherein the unification console is included in a host operating system on the host.

8. The method according to claim 1 further comprising:

enabling a descriptor module to be configured, the descriptor module including configuration information for the host;

launching the VMs in the host according to the configuration information in the descriptor module;

launching the unification console, the unification console capable of interacting with all the VMs according to the configuration information in the descriptor module; and

starting up the unified desktop interface.

9. The method according to claim 8 wherein enabling the descriptor module to be configured further comprises at least one of accepting input from the user to configure the descriptor module, enabling the host to configure the descriptor module, enabling the unification console running on the host computer to configure the descriptor module and enabling the unified desktop interface to configure the descriptor module.

20. The method of claim 1, wherein the composite view does not identify which of the plurality of VMs hosts which of the plurality of applications.

22. The method of claim 1, wherein the composite view comprises a view of which of the plurality of VMs hosts which of the plurality of applications.

10. An article comprising a machine-accessible medium having stored thereon instructions that, when executed by a machine, cause the machine to:

accept input into a unified desktop interface representing an interface for a unification console, the unified desktop interface including a graphical user interface to present a composite view of applications residing within a plurality of virtual machines (“

VMs”

) on a host computer by displaying a plurality of application icons of application residing in the virtual machines;

identify an application corresponding to the input;

identify a VM in which the application resides;

send the input to the application, wherein the input is one of filtered and transformed, and

cause output from the application to be redirected to the unification console, wherein the output is one of filtered and transformed.

11. The article according to claim 10 further comprising instructions that, when executed by the machine, cause the machine to present the output from the application on the unified desktop interface.

12. The article according to claim 10 further comprising instructions that, when executed by the machine, cause the machine:

determine whether the application is currently executing in the VM in which the application resides; and

if not, cause the application to begin executing.

13. The article according to claim 10 wherein the instructions that, when executed by the machine, cause the unification console to identify at least one of the application and the VM in conjunction with a virtual machine manager (“

VMM”

).

14. The article according to claim 10 wherein the instructions that, when executed by the machine, cause the machine to redirect the output to the unification console further comprises instructions that, when executed by a machine, cause the machine to redirect the output from the application from the VM in which the application resides to the unification console.

15. The article according to claim 14 wherein the instructions that, when executed by the machine, cause the machine to redirect the output further comprises instructions that, when executed by a machine, cause the machine to perform one of filtering and transforming the output before the output is redirected.

16. The article according to claim 14 wherein the instructions that, when executed by the machine, cause the machine to redirect the output from further comprises instructions that, when executed by a machine, cause the machine to copy the output from the application from the VM in which the application resides and provide the copy of the output to the unification console.

17. The article according to claim 16 wherein the instructions that, when executed by the machine, cause the machine to copy the output further comprises instructions that, when executed by a machine, cause the machine to perform one of filtering and transforming the output before the output is provided to the unification console.

18. The article according to claim 10 wherein the instructions that, when executed by the machine, cause the unification console to execute in a VM.

19. The article according to claim 10 wherein the instructions that, when executed by the machine, cause the unification console to be included in a virtual machine manager.

21. The article according to claim 10, wherein the composite view does not identify which of the plurality of VMs hosts which of the plurality of applications.

23. The article according to claim 10, wherein the composite view comprises a view of which of the plurality of VMs hosts which of the plurality of applications.
