For the Phenom type, I honestly don't remember why, but there was also a good

Curious, what guests balk at modern hardware but are fine with phenom?
Sles11 GA ;).

Still curious, how does -cpu host break it?

Either way, I don't think we need a phenom2 type. The features additional are 
minor enough to not really matter and all use cases I can come up with require 
either -cpu host (local virt) or -cpu phenom (migration).
I'm fine with this (or with adding phenom2).  But don't make phenom contain 
flags that real phenoms don't have.
Those were my words :).

Then we are in agreement.
