Hi Sivaram,

Here are the two patches for KVM describing what I have done.  I am
continuing to work on it and still mulling a move to virtio.  These
don't apply against the current tree, but I can provide those patches
if you would like to see them.

http://patchwork.kernel.org/patch/38355/

http://patchwork.kernel.org/patch/38347/

We're you interested in using the shared memory for something in
particular or were you just looking for a to-do task to pick up?

Let me know if you have any questions,

Cheers,
Cam
