I think it is/will be important to have a mechanism in place which 
allows the addition of
    software (packages/scripts) to the host image (and build a 
new/custom one (within
    the rules of supportability) by a non-rocket scientist . Ideally it 
would be part of
    the oVirt UI (maybe via an advanced tab and require "special" 
privileges) and
    CLI .

    Maybe another route (or parallel) would to look into a similar 
remote API capability
    like ESX3i/3.5 has for 3rd party monitoring apps. They now have to 
use the remote
    API and no longer can be installed on the host/HV , this also avoids 
the issue of
    someone tinkering with the host image and creating an unsupportable 
environment .
   
    We have had a number of customers asking for this capability 
(Goldman, UBS,
    Lehman, BoA etc..)
