Actually, QEMU can calculate from the values in smp, sockets, cores, threads to emulate how many physical processor, how many cores does each of physical processors contain and how many multi-threading logical processors does each core supports.

The algorithm was explain in my email
https://www.redhat.com/archives/libvir-list/2013-May/thread.html

The results can be verified by using cpuid tool
So I don't think this is a bug. If anything wrong during testing, please reopen this bug again.
