You need to also create the TUN device, e.g.
# tunctl -u david -t uml-david0
...creates a sort-of virtual crossover cable, not yet connected to
anything. I think you can treat 'uml-david0' here as an interface and
give it an IP, then you need to attach the UML to the tun/tap thing
when you start it up.
funnily enough I'm setting up UMLs now too, but I'm using bridging as
well as TUNs. I got the above line from the site
http://uml.openconsultancy.com/ which is helpful. I find
http://www.huckstep.uklinux.net/mle/uml-woody.html one of the most
succinct and mostly accurate guides on creating a user-mode-linux root
partition, if you need help with that.
