I just tried to install the latest DSS (6.0up98.xxxx.7337 2013-02-14 b7337), it's stuck a 72% ?
I restart on old one (6.0up90.8101.5845) it boot perfectly...

I have two OpenE (same hardware), my slave one updated to latest without any problem, the master failed...

i have to move production VM to slave now ... Look my DSS system need some maintenance :/
