Abstract

An event associated with a virtual machine may be identified. Furthermore, a script associated with the event may be identified. A property of a virtual device that is assigned to the virtual machine may be received. A determination may be made to execute the script or not to execute the script for the virtual machine based on the property of the virtual device that is assigned to the virtual machine.

Claims

1. A method comprising:

identifying an event associated with a virtual machine;

identifying a script associated with the event;

receiving a property of a virtual device that is assigned to the virtual machine; and

determining, by a processing device, whether to execute the script or not to execute the script for the virtual machine in view of the property of the virtual device that is assigned to the virtual machine.

2. The method of claim 1, wherein the script is determined to be executed if a value of the property of the virtual device assigned to the virtual machine satisfies a condition of the script.

3. The method of claim 1, wherein the script is determined to not be executed if a value of the property of the virtual device assigned to the virtual machine does not satisfy a condition of the script.

4. The method of claim 1, wherein the script comprises commands associated with operations to be performed on the virtual device of the virtual machine.

5. The method of claim 1, further comprising:

identifying a second virtual machine associated with the event; and

receiving a second property of a second virtual device assigned to the second virtual machine, wherein the executing of the script performs an operation on the second virtual machine if the second property of the second virtual device assigned to the second virtual machine satisfies a condition of the script.

6. The method of claim 5, wherein the executing of the script does not perform the operation on the second virtual machine if the second property of the second virtual device assigned to the second virtual machine does not satisfy the precondition

7. The method of claim 1, wherein the event is an action performed on the virtual machine at a host system.

12. The method of claim 1, the processor is further to:

identify a second virtual machine associated with the event; and

receive a second property of a second virtual device assigned to the second virtual machine, wherein the executing of the script performs an operation on the second virtual machine if the second property of the second virtual device assigned to the second virtual machine satisfies a condition of the script.

13. The system of claim 12, wherein the executing of the script does not perform the operation on the second virtual machine if the second property of the second virtual device assigned to the second virtual machine does not satisfy the precondition.

8. A system, comprising:

a memory; and

a processing device coupled with the memory to;

identify an event associated with a virtual machine;

identify a script associated with the event;

receive a property of a virtual device that is assigned to the virtual machine; and

determine whether to execute the script or not to execute the script for the virtual machine in view of the property of the virtual device that is assigned to the virtual machine.

9. The system of claim 8, wherein the script is determined to be executed if a value of the property of the virtual device assigned to the virtual machine satisfies a condition of the script.

10. The system of claim 8, wherein the script is determined to not be executed if a value of the property of the virtual device assigned to the virtual machine does not satisfy a condition of the script.

11. The system of claim 8, wherein the script comprises commands associated with operations to be performed on the virtual device of the virtual machine.

14. The system of claim 8, wherein the event is an action performed on the virtual machine at a host system.

15. A non-transitory machine-readable storage medium including data that, when accessed by a processing device, cause the processing device to perform operations comprising:

identifying an event associated with a virtual machine;

identifying a script associated with the event;

receiving a property of a virtual device that is assigned to the virtual machine; and

determining whether to execute the script or not to execute the script for the virtual machine in view of the property of the virtual device that is assigned to the virtual machine.

16. The non-transitory machine-readable storage medium of claim 15, wherein the script is determined to be executed if a value of the property of the virtual device assigned to the virtual machine satisfies a condition of the script.

17. The non-transitory machine-readable storage medium of claim 15, wherein the script is determined to not be executed if a value of the property of the virtual device assigned to the virtual machine does not satisfy a condition of the script.

18. The non-transitory machine-readable storage medium of claim 15, wherein the script comprises commands associated with operations to be performed on the virtual device of the virtual machine.

19. The non-transitory machine-readable storage medium of claim 15, wherein the operations further comprise:

identifying a second virtual machine associated with the event; and

receiving a second property of a second virtual device assigned to the second virtual machine, wherein the executing of the script performs an operation on the second virtual machine if the second property of the second virtual device assigned to the second virtual machine satisfies a condition of the script.

20. The non-transitory machine-readable storage medium of claim 19, wherein the executing of the script does not perform the operation on the second virtual machine if the second property of the second virtual device assigned to the second virtual machine does not satisfy the precondition
