Can you expand on how it doesn't run? I would suggest using the master branch and patching it with my patches. As well as patching, you need to run with something like -ivshmem 128,myshm to actually create the shared memory device. > I have checked out the qemu-kvm-0.11.0 and built and installed but then > I get a version miss-match.

I hope so :) I'm currently working on some suggested changes from the Qemu/KVM developers.
