[uml-user] Tap device does not appear in /dev

[Erik de B. - L. <Erik@LowVoice.nl>]

Hi List,

I'm setting up tap devices for some UML boxes that I intend to run on public
IP's. I'm avoiding the use of both NAT and bridging. I have tuntap and
dev_netlink built-in in the host kernel.

I've made the /dev/net/tun node with:
# mknod -m 660 /dev/net/tun c 10 200
Setting up the tap device seems like no problem:
# tunctl -u uml2 -t tap2
Set 'tap2' persistent and owned by uid 2002
# ls -alR /dev |grep tap
[no relevalt results, no tap devices were created]

Creating taps with other tunctl parameters doesn't seem to work either.

On the host I can ifup tap2 and do anything with it, but the node was never
created... I've done all this before on another host and the tap devices
were created automatically. What can I do, or what am I doing wrong?

Best regards,
