[gentoo-user] Qemu tun/tap privledge problem: HOWTO is wrong?

[Grant Edwards]

I've followed the HOWTO at http://gentoo-wiki.com/HOWTO:_Qemu,
but the section on TUN/TAP networking appears to be wrong where
it says

  I would recommend that you create the tap device with
  ownership to the user running qemu as follows
  
    tunctl -u <user> -t tap0 

  This prevents having to run qemu as root in >=2.6.18 

Even though I created tap0 with the command shown, I still have
to run Qemu as root or I get the following error:

qemu -kernel-kqemu -localtime -hda w2kdisk.img -net nic 
     -net tap,ifname=tap0,script=/usr/local/etc/qemu-ifup

warning: could not open /dev/net/tun: no virtual network emulation
Could not initialize device 'tap'

If I run qemu as root, it works fine.
