I doubt that this is the cause of the failure, as vdsm has always
reported "0" for ib devices, and still is.

Does a former version works with your Engine?
Could you share more of your vdsm.log? I suppose the culprit lies in one
one of the storage-related commands, not in statistics retrieval.

Since "latest master" is an unstable reference by definition, I'm sure
that History would thank you if you post the exact version (git hash?)
of the code.
