Performing application specific actions without in-guest credential information

1. A method comprising:

receiving, by a virtual machine (VM), a notification that a media image is mounted on a virtual media device of the VM, the media image including a message for one or more applications running in the VM, the message including commands that cause the one or more applications to perform operations;

enabling, by the VM, an agent in the VM to access the virtual media device and retrieve the message from the media image;

causing, by the VM, the agent to communicate the message to the one or more applications running in the VM; and

enabling, by a guest operating system associated with the VM without requiring credential information, the one or more applications running in the VM to perform the operations based on the commands included in the message, the virtual media device being a CDROM, the media image is an International Standards Organization (ISO) image, and the one or more operations in the VM including post processing operations of a backup operation.

2. The method of claim 1 , wherein the agent is configured to verify that the media image is generated by a permissible source and to retrieve the message from a known location in the media image.

3. The method of claim 1 , further comprising enabling the agent to cause the virtual media device to eject based on completion of the operations.

4. The method of claim 1 , further comprising enabling the agent to update the media image with status information based on completion of the operations.

5. The method of claim 2 , wherein the guest OS associated with the VM is further configured to enable the one or more applications to perform the operations without requiring the credential information in response to the media image being mounted on the virtual media device by a permissible source.

6. A computer program product comprising computer-readable program code to be executed by one or more processors when retrieved from a non-transitory computer-readable medium, the program code including instructions to:

receive a notification that a media image is mounted on a virtual media device of a virtual machine (VM), the media image including a message for one or more applications running in the VM, the message including commands that cause the one or more applications to perform operations;

enable an agent in the VM to access the virtual media device and retrieve the message from the media image;

cause the agent to communicate the message to the one or more applications running in the VM; and

enable, by a guest operating system associated with the VM without requiring credential information, the one or more applications running in the VM to perform the operations based on the commands included in the message, the virtual media device being a CDROM, the media image being an International Standards Organization (ISO) image, and the one or more operations in the VM including post processing operations of a backup operation.

7. The computer readable medium of claim 6 , wherein the agent is configured to verify that the media image is generated by a permissible source and to retrieve the message from a known location in the media image.

8. The computer readable medium of claim 6 , further comprising enabling the agent to cause the virtual media device to eject based on completion of the operations.

9. The computer readable medium of claim 6 , further comprising enabling the agent to update the media image with status information based on completion of the operations.

10. The computer readable medium of claim 6 , wherein the guest OS associated with the VM is further configured to enable the one or more applications to perform the operations without requiring the credential information in response to the media image being mounted on the virtual media device by a permissible source.

11. A system comprising:

a processor-based application executed on a computer system and configured to:

receive a notification that a media image is mounted on a virtual media device of a virtual machine (VM), the media image including a message for one or more applications running in the VM, the message including commands that cause the one or more applications to perform operations;

enable an agent in the VM to access the virtual media device and retrieve the message from the media image;

cause the agent to communicate the message to the one or more applications; and

enable, by a guest operating system associated with the VM without requiring credential information, the one or more applications running in the VM to perform the operations based on the commands included in the message, wherein the virtual media device is a CDROM, the media image is an International Standards Organization (ISO) image, and the one or more operations in the VM including post processing operations of a backup operation.

12. The system of claim 11 , wherein the agent is configured to verify that the media image is generated by a permissible source and to retrieve the message from a known location in the media image.

13. The system of claim 11 , further comprising enabling the agent to cause the virtual media device to eject based on completion of the operations.

14. The system of claim 11 , further comprising enabling the agent to update the media image with status information based on completion of the operations.

15. The system of claim 11 , wherein the guest OS associated with the VM is further configured to enable the one or more applications to perform the operations without requiring the credential information in response to the media image being mounted on the virtual media device by a permissible source.
