Please check the documentation. There's the -machine option with parameters such as pc-1.0 and pc-1.2 for that exact purpose. libvirt should supply the corresponding option automatically. More difficult is if you're trying to migrate from qemu-kvm to qemu - code changes to your copy of 2.0 will be necessary then.
