Probably you should do as root "tunctl -u mwuml004 -t mwuml004" to create such an interface and assign it to that user, and only then start the UML. Also make sure that /dev/net/tun is readable to UMLs (a UML group is usually used - with udev things don't persist after reboot). > So I start up the UML server: > > su - mwuml004 /home/mwuml004/bin/mwuml004 > > and ps -fu mwuml004 reveals all kinds of exciting things going on there, > until the thing boots up and settles down into normality.
