That affects all kernels, because that needs kvm modules parameter enable_vmware_backdoor. I am not comfortable enabling that by default on our kernels. We could enable that during the kvm-unit-tests. But for now, on our own branch of kvm-unit-tests, I decided to simply disable that test to be run by default.
