[Yoav Kleinberger]

Maor can you please explain? I'm not familiar with this audit log

I would like to suggest another solution,
Why not let the audit log present the extra error description.
VDSM can override the existing error message before returning it to the
engine with the extra data.

that way you will not have to add  new attributes to the existing API,
and the dialog messages will still be localized.

regards,
Maor
