Some embodiments of the inventive subject matter are directed to receiving a request from a first instance of an operating system (e.g., a virtual operating system) to load a kernel extension that extends functionality of a kernel, where the kernel extension may be shared by a second instance of the operating system. An indicator accessible only to the second instance of the operating system records an indication that the first instance of the operating system requested to load the kernel extension. The kernel extension is loaded. A request is received by the first instance of the operating system to remove the functionality from the kernel. The functionality is removed from the kernel in response to determining, based on the indicator, that the first instance of the operating system had previously requested to load the kernel extension. |
