Abstract
Some embodiments of the inventive subject matter are directed to detecting a request to access a symbol via a special file that accesses kernel memory directly. The request can come from an application from a first instance of an operating system (OS) running a first version of the OS. A second instance of the OS, which manages the first OS, receives the request. The second instance of the OS includes a kernel shared between the first and second instances of the OS. The second instance of the OS runs a second version of the OS. Some embodiments are further directed to detecting data associated with the symbol, where the data is in a first data format that is compatible with the second version of the OS but is incompatible with the first version of the OS. Some embodiments are further directed to reformatting the data from the first data format to a second data format compatible with the second version of the OS.
