Hi! Just in case, just so you know. I've tried FreeBSD 10-STABLE r270125 with vt(4) on Hyper-V (Win Server 2012 DataCenter). Its performance is extremely bad (while syscons is ok). Here is video http://www.youtube.com/watch?v=62CIKCJ7bog P.S. vt(4) is a bit faster on VirtualBox though when I tried it last time.
