Abstract
Some embodiments include a method of preventing software licensing exploitation in a virtual environment. The method includes: retrieving, by a first instance of a licensed application running on an original virtual machine as permitted by an original software license, an original unique identifier from a virtual device in the original virtual machine; creating, by a hypervisor of the virtual environment, a cloned virtual machine instance as a copy of the original virtual machine; retrieving, by a second instance of the licensed application running on the cloned virtual machine instance, a new unique identifier from a virtual device in the cloned virtual machine instance; and determining, by the second instance of the licensed application running on the cloned virtual machine instance, that the original software license does not apply to the cloned virtual machine instance because the new unique identifier is different from the original unique identifier.
