Firstly, CPU topology and model with optional features have to be advertised in host capabilities:
<host> <cpu> <arch>ARCHITECTURE</arch> <features> <!-- old-style features are here --> </features> <model>NAME</model> <topology sockets="S" cores="C" threads="T"/> <feature name="NAME"/> </cpu> ... </host>
Secondly, drivers which support detailed CPU specification have to advertise it in guest capabilities:
<guest> ... <features> <cpuselection/> </features> </guest>
And finally, CPU may be configured in domain XML configuration:
<domain> ... <cpu match="MATCH"> <model>NAME</model>
Note that for qemu/kvm we plan of using the model only. The features (flags) below will be a function of the model used. Model is one of core2duo/Nehalem/Merom/...
<topology sockets="S" cores="C" threads="T"/> <feature policy="POLICY" name="NAME"/> </cpu> </domain>
