Sorry for this lag. This week a lot of interesting news appeared about actual and upcoming virtualization products but my DELL Inspiron 5150 decided to stop working.
I had a problem with the power socket, solded on the motherboard. Luckily my 3 years warranty solved the problem: I called DELL customer care and their technician arrived at my company office the day after, replacing my motherboard in just a couple of hours. A totally satisfying experience indeed.
I will start posting again tomorrow.
