Hi Mohammed,
A shared memory transport would be a new addition to the code base so
there isn't anything yet "in KVM". That said, I'm working on my patch
and it will hopefully be accepted soon. Frankly, while I suggested
this project, I'm not sure there's enough work remaining for the full
Summer.

My patch currently supports guest-to-guest communication and
guest-to-host. I'll be sending out a new version shortly. You can
see if there's something you might like to add to it whether it's part
of GSoC or not.
