As here in Europe Christmas eve has already begun, we, the OSNews team, both editors and site maintainers, would like to wish all of our readers a very merry Christmas. May everyone be with the ones they love-- no matter one's nationality, religion, favourite operating system, favourite desktop environment, or whatever. Let us also hope the victims of the tsunami, the earthquake in Pakistan, and Gulf Coast hurricane, and all others who have suffered this year, have found comfort. Let's have a moment of silence on the 26th for them. Merry Christmas, people (and anyone who dares to sing "Last Christmas" in the comments gets banned for a week) !

As the end of the year approaches, it appears that virtualization's time in the open source spotlight has all but come.

And, now, it looks ready to burst next year.
