[Qemu-discuss] Setting CPU features

[Glandvador]

Hi,

I want to emulate my headless embedded device  with a virtual machine, 
as it is much easier to test upgrades. I am able to set the RAM amount, 
the NIC interfaces, harddrives, etc., but I didn't yet found a way to 
set a CPU with specific features. My CPU is an AMD Geode LX which is 
mostly a i686, but without some instructions. The most important missing 
instruction(s) are the NOPL ones. This instruction can be generated by 
binutils, depending of parameters.
In the past, I have already been touched by this problem, when Fedora 
released a glibc with this instruction enabled. On the virtual machine 
the upgrade gone smooth, but on real system it was a nightmare.

So, it is a way with qemu to set a i686 CPU without some instructions?
