Journalling in VM?

Is there any point to running a journalling file system inside a virtual
machine? As long as the host machine has a reliable file system, even if
the host crashes, the memory image should be recoverable so that the VM's
file system survives.

There are certainly scenarios in which the file system might not close
cleanly, but I'm wondering whether the probability is so low that the
overhead of journalling doesn't pay.
