I had watched the nice video which posted by Duncan from yellow bricks days back. The video had showed some “GREAT” result and excellent BLUE SCREEN that every administrator will not want it to be happened to themself. Windows Servers running on HypverV and getting bunch of blue screen is not a joke. You should reconsider to put your mission critical environment with HyperV rather than VMware and Xen.

You can read more about the article from here and watch the nice video too.

Have fun.
