The qemu32/qemu64 models are weird in that the exact combination of CPUID flags does not match any actual processor. kvm32 and kvm64 are a better match when not using TCG. Use them when -cpu is only needed to hardcode a 32-bit guest arch or for kvmclock.
I don't think we can do this as it means the guest CPU may change unexpectedly for existing domains. A 32b domain started on current libvirt would see qemu32, while the same domain started after this patch would see kvm32. Jirka
