I want to set up a virtual machine (kvm/qemu) that runs on a headless host. The guest should run a Linux system (preferebly Ubuntu Server) that runs a single non-headless application. This should be accessible via a remote desktop tool.

The key is I want to install/run as less of X11, etc. as possible.

This has been giving me (and other people) headache for some time now. I don't even know anymore what I've tried so far so I want to start from scratch.

I know this is kind of a general/big question but you guys are my last hope :-)

I've been doing something similar. the easiest way I can think of is to install X and the application, as well as the minimum dependencies, then use X forwarding to view the application.

On Linux/Mac it's as simple as ssh -X host app, and there are apps to do it from windows as well with a third-party application.

The problem with that would be that the application stops running if I close my SSH client. I want it to continue running even if I'm not looking at it. – André Stannek Oct 31 '12 at 19:18
In that case, I would recommend looking into X11VNC – ssmy Nov 1 '12 at 20:25
