I have "Intel(R) Core(TM) i5-3330 CPU @ 3.00GHz" on a physical host
machine.  I'd like to emulate a cpu with the "movbe" instruction set.
Doing some testing, I tried, as root stuff like...

qemu-system-x86_64 -enable-kvm -cpu Broadwell

...and got the following warnings
warning: host doesn't support requested feature: CPUID.01H:ECX.fma [bit 12]

  On real qemu sessions "grep movbe /proc/cpuinfo" doesn't get any hits.
I hope I'm doing something wrong here, rather than qemu not being able
to emulate a newer cpu.  Any ideas?
