This looks a lot like a new manifestation of: 
https://bugzilla.redhat.com/show_bug.cgi?id=1057772

I even instrumented the code in 
/usr/lib64/python2.7/site-packages/vdsm/netinfo.py

The device name ("p3p1") being passed in is correct (I even tried 
setting the string directly), but the returned object is empty.

If I start python by hand and run ethtool.get_interfaces_info("p3p1") it 
returns the correct data.

So it seems as though the code is somehow environmentally sensitive. I'm 
not sure what it is about my environment that would cause issues here 
however, since presumably this is working for others...
