My guess has led us nowhere, since etree.ParseError is simply missing
from python 2.6. It is to be seen only in python 2.7!

That's sad, but something *else* is problematic, since we got to this
error-handling code.

Could you make another try and temporarily replace ParseError with
Exception?

    sed -i s/etree.ParseError/Exception/ /usr/share/vdsm/gluster/cli.py

(this sed is relative to the original code).
