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! :-)
