[gentoo-user] Qemu tun/tap privledge problem: HOWTO is wrong?
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. -- Grant Edwards grante Yow!

You also have to chmod go+rw /dev/net/tun (if you haven't already), and probably modify the related udev rule to make the change persistent. -- [EMAIL PROTECTED] mailing list
