I'm trying to get each display on a computer available to a Linux guest (Ubuntu 13.04) provided as a separate virtual device. But instead of doing this, I get one virtual device in xrandr and the additional display is a mirrored version of it.
This is my xrandr output. Only Virtual1 shows up, I expect to see a Virtual2.

The device is a retina MBP with an Ubuntu Server 13.04 Guest, I am pretty sure the guest additions were "easy installed". The external display is connected over HDMI. My window manager is i3wm.
