Method and system for software licensing under machine virtualization
A method and system implementing software licensing management under machine virtualization are disclosed. According to one embodiment, a system comprises a virtual platform running on a physical machine; a binding agent running on a host operating system of the virtual platform; a license enforcement module running on a virtual machine instance of the virtual platform. The license enforcement module is in communication with the binding agent. The binding agent enforces a mutex lock to ensure that only a specified number of license enforcement modules are running on the physical machine.
1. A system for managing software licensing, the system comprising:
a processor of a physical machine, wherein the processor executes instructions stored in memory and wherein execution of:
a binding agent running on a virtual platform extracts physical binding information of the physical machine, and
a license enforcement module associated with a license and instantiated on a virtual machine hosted on the virtual platform, wherein a license file associated with the license specifies that the physical machine is allowed to run only a specified number of license enforcement modules, the license enforcement module executed to:
maintain heart-beat contact with the binding agent,
communicates with the binding agent to determine whether the extracted physical binding information of the physical machine corresponds to the license file and whether there is another machine with the same physical binding information associated with the binding agent, and
enforces a mutex lock to ensure that no more than the specified number of license enforcement modules are running on the physical machine specified by the license file.
2. The system of claim 1 , wherein the specified number of license enforcement modules is one.
3. The system of claim 1 , wherein the heart-beat communication between the binding agent and the license enforcement module allows for configuration of parameters of the license enforcement module.
4. The system of claim 1 , wherein the license enforcement module is reconfigured based on instructions from a software vendor providing software under the license.
5. The system of claim 1 , wherein the physical binding information is selected from the group consisting of an Ethernet address, an IP address, and a disk volume serial number.
6. The system of claim 5 , wherein the license enforcement module compares the extracted physical binding information to a platform type and a hostID type specified by the license file.
7. A method for managing software licensing, the method comprising:
executing instructions stored in memory of a physical machine, wherein a processor of the physical machine executes:
a binding agent on a virtual platform, the binding agent being executed to extract physical binding information of the physical machine;
a license enforcement module associated with a license and instantiated on a virtual machine hosted on the virtual platform, wherein a license file associated with the license specifies that the physical machine is allowed to run only a specified number of license enforcement modules, the license enforcement module being executed to:
maintain heart-beat contact with the binding agent,
communicate with the binding agent to determine whether the extracted physical binding information of the physical machine corresponds to a license file associated with the license and whether there is another machine with the same physical binding information associated with the binding agent, and
enforce a mutex lock to ensure that no more than the specified number of license enforcement modules are running on the physical machine specified by the license file.
8. The method of claim 7 , wherein the specified number of license enforcement modules is one.
9. The method of claim 8 , wherein the heart-beat communication between the binding agent and the license enforcement module allows for configuration of parameters of the license enforcement module.
10. The method of claim 8 , further comprising reconfiguring the license enforcement module based on instructions from a software vendor providing software under the license.
11. The method of claim 10 , wherein the physical binding information is selected from the group consisting of an Ethernet address, an IP address, and a disk volume serial number.
12. The method of claim 10 , wherein the license enforcement module compares the extracted physical binding information to a platform type and a hostID type specified by the license file.
13. A non-transitory computer-readable storage medium, having embodied thereon a program executable by a processor to perform a method for managing software licensing, the method comprising:
executing a binding agent on a virtual platform, the binding agent being executed to extract physical binding information of the physical machine;
executing a license enforcement module associated with a license and instantiated on a virtual machine hosted on the virtual platform, wherein a license file associated with the license specifies that the physical machine is allowed to run only a specified number of license enforcement modules, the license enforcement module being executed to:
maintain heart-beat contact with the binding agent,
communicate with the binding agent to determine whether the extracted physical binding information of the physical machine corresponds to a license file associated with the license and whether there is another machine with the same physical binding information associated with the binding agent, and
enforce a mutex lock ensure that no more than the specified number of license enforcement modules are running on the physical machine specified by the license file.
