We can probably default -enable-kvm to -cpu host, as long as we explain

Hardware upgrades or software upgrades?
Yes.
I just want to remind all the the main motivation for using -cpu
realModelThatWasOnceShiped is to provide correct cpu emulation for the
guest. Using a random qemu|kvm64+flag1-flag2 might really cause trouble
for the guest OS or guest apps.
On top of -cpu nehalem we can always add fancy features like x2apic, etc.
