[libvirt] virGetNodeinfo .cpus

[Zvi Dubitzky]

virNodeGetInfo()  returns .cpus as 2  but the  /proc/cpuinfo of the node 
shows 2 processors with 2 cores each  ('cpu cores')  . Or maybe the 'core 
id' is what
counts in the /proc/cpuinfo  and that  one gets vaue 0  , 1 only  i.e 
totally 2 

can you clarify  ?

Here is the output of /proc/cpuinfo:
