Looking at linux kernel code, they have some quirks based on cpu model
number && vendor
nehalem is .family = 6, .model = 26,
kvm64 is .family = 15, .model = 6
qemu64 is.family = 15, .model = 107,
maybe it could be interesting to test with adding flags from
qemu64/kvm4 to see if it's the same behaviour ?
from kvm64, xf86-64-v2 is
'+lahf_lm,+popcnt, +sse4.1,sse4.2, +ssse3' (and optionnal +aes)
(and we already enable lahf_lm by default in QemuServer/CPUConfig.pm )
