It needs 2 Video cards. One for host. One for guest. Keyboard and mouse is usually shared but you can do dedicated pass through of those things as well as usb peripherals if you want. I can report that the oculus works fine in a vm with vga pass through. On my setup, I use both monitors for linux and then when i want to start up a game I boot a vm of windows 7 and switch one of the monitors inputs over to it. The performance is roughly the same as native. Since I play with v-sync on and have a fairly powerful graphics card for gaming, I can't tell a difference between native and vm. But when turning off v-sync, I do notice a 5-8% drop in frame rate. I feel it's worth it since i do everything in linux and it was a pain to duel boot. But, it's not for everyone.

Alpine has a touch screen stereo that vibrates the screen when you touch a button. It has different vibrations for different buttons. Gives you plenty of feedback. I wish computer makers would add something like that to their touchscreens.
