Hi,
I did this with Mountain Lion on VBox on Win7 (64) host on an Alienware M11x R3 (i7,8GB) and it works fine. The only things I'd like to fix, are the keyboard layout (which I haven't taken the time to search for a fix) and the graphics part, for everything is a bit too laggy. For the graphics part, I've found several threads here that tell how to fix things on a hackintosh; but not for a VM. Do you have any recommendations?
Thanks in advance
