Although if memory was able to be unplugged, the Linux guest would have
reset the memory to private when it was done with the memory. But from
a interface perspective, it seems weird to require the guest to signal
this because private/shared state is ultimately controlled by the host.
Unlike accept state where the guest gets some say.
