It seems like the interesting traceback should be further up - I
suppose self._irs failed initialization and kept its original None
value. Please scroll up and try to find out why this failed on Vdsm
startup.

We have a FIXME in vdsm so that we report such failures better:

vdsm/BindingXMLRPC.py: # XXX: Need another way to check if IRS init was okay

Adam, could you take a further look into this?
