Hi Simon/Gianluca[/all], 

Many thanks for reporting the issues that you have encountered. 

In order to better track them, please file a BZ for each scenario 
in which you encounter such an alert in the UI. 

For each such BZ, please include:

- Exact oVirt version in which the alert has appeared. 

- Steps to reproduce (that lead to the displayed alert). 

- The full exception stack-trace from the client side (javascript) 
log [like the one that Simone has provided in his last response 
[1] / like the one that appears in the screen-shot provided by 
Gianluca [2]] - please provide the actual text though, rather 
than a screen-shot of the text, as it will ease the problem-
tracing process for us. 

- If relevant: server side engine.log. 

----
Regards,
Einav
