Line 153: 
Line 154:     for iface in iscsi.iterateIscsiInterfaces():
Line 155:         if iface.name == ifaceName:

Line 157:                 if iface.netIfaceName is None:
Some comments:

* it was hard to find the positive case that we're interested about, what we're 
really looking for here (just as for the name) is the case where netIfaceName 
== iface.netIfaceName (not sure if there's anything we can do about  this one, 
I didn't find any good suggestion to give here)

* I would have moved the "update" logic to its own function

My personal taste would have gone for something like:

 for iface in iscsi.iterateIscsiInterfaces():
     if iface.name != ifaceName:
         continue

     if netIfaceName is not None:
         updateIfaceNameIfNeeded(...)
         if iface.netIfaceName != netIfaceName:
             logging.error(...)
             raise se.iSCSIifaceError()

     return iface
Line 158:                     iface.netIfaceName = netIfaceName
Line 159:                     iface.update()
Line 160:                 elif netIfaceName != iface.netIfaceName:
Line 161:                     logging.error('iSCSI netIfaceName coming from 
engine [%s] '
