Well, if there is just one machine in the whole of QEMU that does not have a 
default CPU anymore, that calls for trouble, I think (as we can already see 
in this series where you have to rework a lot of qtests). It's likely better 
to set another CPU as default in that machine in that case. What about 
simply using "max" or "host" if TCG is disabled there?
