That's a shortcoming in that particular version of QEMU then. The KVM interface still allows to do everything you could do with -cpu host with an explicit CPU define. If user space wants, it could write away the host CPU type and try to live migrate that machine to another machine then with the explicit target vcpu id. Please keep in mind that we're talking about the generic KVM / user space interface here, not the actual QEMU implementation.
