This patch set enables cpu model support for s390. The user can now set exact cpu models, query supported models via virsh domcapabilities, and use host-model and host-passthrough modes. The end result is that migration is safer because Qemu will perform runnability checking on the destination host and quit with an error if the guest's cpu model is not supported.
A slightly (un)related question: is QEMU going to implement unavailable-features for s390? In other words, will libvirt users be able to easily see what CPU models can be used on a host? The libvirt code should be ready so it's just a matter of making QEMU report unavailable-features. Jirka
