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?

You should choose the newest family that matches all your servers, so you have all of them with the same set of features available. In the list above, SandyBridge is the newest. You can see the hierarchy here: /usr/share/libvirt/cpu_map.xml

Thanks! :-)
