I've launched an Ubuntu 11.10 instance (oneiric-server-cloudimg-amd64-disk1.img downloaded from here) inside of KVM, with VNC enabled. I can connect to the instance using VNC, and I see a login prompt.
I'd like to be able to use this VNC connection to show an X session instead of a text prompt. What do I need to install/configure so that this VNC session exposed through KVM shows an X11 session?
(Note that I can successfully switch between tty[1-6] by doing Ctl-Alt-F#).
