What about installing and pre-configuring Xnest on the image? With a suitable script calling xhost on the host, it just works. This project did it: http://umlbuilder.sourceforge.net/ although it stopped working for me ages ago (probably for some UML bug). I built a Mandrake image (that I now lost) with Xnest configured. With a script on the host which passes the host IP and that calls xhost, it should work easily. And btw, we need a standard startup script anyway. > It would also make it a lot easier to focus on writing a management UI, > hell if there isn't one shortly after, I'll do one myself! Why not one management UI running from the host, a-la vmware? Possibly, with as much code as possible in scripting languages, for better transparency. > Think of a UML browser image (running IE via wine in a limited image > with just X + wine + IE - I would much prefer that to having wine+IE > installed locally), testing framebuffer apps like gtk-fb/cairo-fb > without risking your dev environment, etc... > > Antoine -- Inform me of my mistakes, so I can add them to my list!
