Christy,
psutil.NUM_CPUS reflect the **online** (as described on commit message
and documentation) cores. This is the same number that the host OS
recognize to all operations, that means, the same number of available
cores on /proc/cpu_info and the same number of the command "ppc64_cpu
--cores-on".
This patch goal is provide to user the information of how many available
cores the host system has at runtime. I still support this patch to
reflect this new information.
Regards,

So are we going for CPUs (and let the user figure out how many virtual
CPUs he/she can consoume), or cores (which I think is more useful)?
For SMT/hyperthreading , I'm using ppc64_cpu and virsh capabilities:
<capabilities>
<host>
<uuid>412bb869-1795-46e9-9bb3-dfe12f3bb45d</uuid>
<cpu>
<arch>x86_64</arch>
<model>SandyBridge</model>
<vendor>Intel</vendor>
<topology sockets='1' cores='2' threads='2'/>
$ ppc64_cpu --cores-on
