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