Summary: CPU ID Emulation bug: AMD Athlon

Initial Comment:
Qemu incorrectly emulates CPU ID of AMD Athlon CPU.

Namely:
1. It uses CPU Model of "Qemu CPU"
2. It shows SSE/SSE2 instructions as CPU flags, while AMD Athlons don't have it.
3. When running KVM on Intel CPU, it shows "CPU vendor" as Intel instead of AMD.
In my opinion KVM should refuse to emulate AMD Athlon CPUID on Intel CPUs, due to lacking 3Dnow! (unless those instructions can be emulated)
