Tried this on with two versions of QEMU (0.12.50 out of CVS) and qemu-
kvm 0.12.1:
QEMU emulator version 0.12.50, Copyright (c) 2003-2008 Fabrice Bellard
QEMU PC emulator version 0.12.1 (qemu-kvm-devel), Copyright (c) 2003-2008 Fabrice Bellard
model name : Intel(R) Xeon(R) CPU E5520 @ 2.27GHz
In both cases I am able to specify the sse4.1 and sse4.2 flags without
problems.
Are you building QEMU with strange flags, or running binaries from a
vendor somewhere?
Cheers,
Jes

I'm testing as-shipped w/ Fedora 12 and 13. Other flags (+ssse3) seem
to work fine.
Thanks for taking a look.

Ok, building from source now:
Passing SSE4.* to the guest does not work for me thru qemu-kvm-0.12.4,
but it _does_ work at current head (git:aa22e82, 0.12.50). I can bisect
further if anybody cares...
