The kernel. On linux for instance, this

    $ ps aux | grep acpi

turns up the following kernel process on my machine:

    root 663 0.0 0.0 0 0 ? S< Oct29 0:00 [ktpacpid]

I think the question is the reverse: not what program implements the VM but which programs run on it and what are they doing? at least that is what I'm asking.
