WSv has a new name, too.

From the "I knew this was coming a long time ago, but wasn't allowed to tell you" department:

Windows Server virtualization - or WSv as we've been calling it - is now called something different.  The new, official name - announced at TechEd IT Forum in Barcelona, Spain - is "Hyper-V"

"Hyper-V? Is that a letter V, or a roman five?"

It's a V-for-Virtualization, I'm betting.  If it were Hyper-Five, they might be referring to my kids (2 boys, 2 girls, and one dog.)

Check out the official Hyper-V page.  The Hyper-V team (an energetic bunch, to be sure) also has a blog: Windows Virtualization Team Blog
