KVM Shared memory ivshmem enquiry

[Neville Clark <nev@zavalon.com>]

Cam and others,

I have been trying to enable Shared memory in KVM but I am not clear on
the correct procedures and requirements, I am new to KVM, kernel
building, git so am on very step learning curve.

I have an application that requires shared memory between host and
guest. I have been using Vmware workstation 6.0.5, but all later
versions do not support shared memory, and WS 6 is no longer available.

I think I have managed to build and install the guest's kvm_ivshmem
module, from http://www.gitorious.org/nahanni/
I used cd kernem_modules;make;sudo make install;sudo modprobe
kvm_ivshmem. Every thing seems to have worked.

On the host side I am very confused as to what is required.
I have created git repository using 
git clone git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git

I have been able to patch, build and install, but the result does NOT
run.
I have checked out the qemu-kvm-0.11.0 and built and installed but then
I get a version miss-match. (this was unpatched as the patch does not
work on this version).

The host is Ubuntu 9.10 64 bit, with ubuntu's KVM installed.

Can I simply somehow build and install ivshmem module, or do I need to
rebuild the kernel? eg get kvm.git and build and install new kernel.
Is there another KVM binary that I can use, instead of Ubuntu's?

Is the ivshmem patch likely to be accepted anytime soon?

Thanks Nev
