2.) Change links from '/admin-guide-cloud/' to
    '/admin-guide/' within the Admin Guide.

Multipath call failed exit
==========================
Problem
~~~~~~~
Multipath call failed exit. This warning occurs in the Compute log
if you do not have the optional ``multipath-tools`` package installed
on the compute node. This is an optional package and the volume
attachment does work without the multipath tools installed.
If the ``multipath-tools`` package is installed on the compute node,
it is used to perform the volume attachment.
The IDs in your message are unique to your system.
