There's no Intel CPU with family=6,model=2, and Linux and Windows guests disable SEP when seeing that combination due to Pentium Pro erratum #82. In addition to just having SEP ignored by guests, Skype (and maybe other applications) runs sysenter directly without passing through ntdll on Windows, and crashes because Windows ignored the SEP CPUID bit. So, having model > 2 is a better default on qemu64 and qemu32 for two reasons: making SEP really available for guests, and avoiding crashing applications that work on bare metal. model=3 would fix the problem, but it causes CPU enumeration problems for Windows guests[1]. So let's set model=6, that matches "Athlon (PM core)" on AMD and "P2 with on-die L2 cache" on Intel and it allows Windows to use all CPUs as well as fixing sysenter.
