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.
