Hi,
... Gerd's above metadata change is dated 2016-03-21, at which point both QEMU v2.4.0 and v2.5.0 had been tagged (on 2015-08-11 and on 2015-12-16, respectively). I guess Gerd may have mis-remembered the exact QEMU release which included SMM support?
Either that, or because some of the bits needed for secure boot didn't made it into 2.4 (and secure boot being *the* use case for smm emulation).
... Anyway, looking over your patch quickly, I think it really only concerns itself with "-machine smm=on", and for that, the 2.4 version check should suffice. It's only OVMF that needs a lot more than that.
Well, in kvm mode there is also a kernel support for smm required ... cheers, Gerd
