No it won't - you get the right stats according to which object you call
the method on.  Remember that python is object oriented.  There's a
difference between:

conn.getCPUStats => virNodeGetCPUStats


dom.getCPUStats => virDomainGetCPUStats

However, this _does_ point out that for consistent capitalization with
existing python bindings, we want to name it getCPUStats, not getCpuStats.

No, getCPUStats is sufficient.  And careful to avoid typos - it's Stats,
not States.
