    The patch follows the same way shm swap out pages. The only difference
    is kvm is a module but shm not. why kvm can't use the symbols shm used?

    Sure, it's possible to write guest memory to a file so not use the
    symbols, if you really hate this, I'll consider the alternative method.

    Thanks,
