We do have an RFE to choose the CPU model in libvirt, but that wouldn't
let us specify topology, since QEMU doesn't allow that to be expressed
via its -cpu arg at this time.
I've just been pointed to this proposed enhancement to QEMU for
choosing topology:
http://patchwork.kernel.org/patch/33961/
That discussion is still ongoing, but once its settled we'll be able to
look at supporting it in libvirt too.

It seems, that qemu is the "problem".
I bought a quad core cpu in the hope, i can use all four cores, but only
2 of them in the host are under full load if i heat up
all cpus in the guest with prime95, superpi or some other programs.
