Apart from the evil that will do to measuring CPU util (like just about 
any virtualization IIRC), I don't think that matters here.  And we are 
somewhat far from CPU util issues.

Those two stem from the code being picky about finding a netperf4 entry 
in /etc/services

Also, unlike netperf2, you cannot just launch the netperf4 netperf 
command bare like that.  It requires a config file and a command file be 
passed to it.  That is one area where the XML comes-in.  There are IIRC 
some examples in doc/ - caveat - the netperf.html there is an older 
version of the netperf2 manual and so has no bearing on netperf4.
