[ovirt-users] CPU family: which should I choose?

[Alan Murrell]

Hello,

I am a bit confused about the CPU families.  When I installed my host, 
it prompted me for the CPU family to use, and gave me a list of CPU 
models to choose from.  I chose the default suggestion, model_SandyBridge.

I don't recall all the choices it gave me offhand, but when I run ' 
vdsClient -s 0 getVdsCaps | grep -i flags ; echo -e -n "\n" ;cat 
/proc/cpuinfo | grep "model name" | head -n 1', it indicates the 
following models detected:

model_Nehalem
model_Conroe
model_coreduo
model_core2duo
model_Penryn
model_Westmere
model_n270
model_SandyBridge

Which one would provide the most compatibility?  Is there a list of CPU 
family "hierarchies" which would indicate what model(s) could fit with what?

Thanks! :-)
