Now I feel like a complete idiot ;-)

Yeah, that solved the problem. Somehow I didn't check the permissions
'cause I thought this was all dealt by giving the '-u <user>' in the
tunctl command. It didn't occur to me that this uml_switch was
completely decoupled.

For a single instance of UML this is now my setup. As root I run

  tunctl -u ingo -t uml0
  ifconfig uml0 192.168.10.1 up
  uml_switch -tap uml0 < /dev/null > /dev/null &
  chown ingo /tmp/uml.ctl
  iptables -A POSTROUTING -t nat -s 192.168.10.0/24 -j MASQUERADE
  echo 1 > /proc/sys/net/ipv4/ip_forward

And then as user

  linux eth0=daemon

where in the root filesystem I've configured that machine to have IP
192.168.10.2.

Now I'm ready for the multi-instance setup ;-)

Thanks,
Ingo
