Please do *NOT* do that. I'm still unconvinced that this isn't just a
subset of the vmclone work that needs to be done in conjunction with
the RNG, and I'd like to get those recent virtio patches merged first
before we move onto this, so we can see where this fits in
holistically. I would not be happy if this got merged prematurely.
