Yep. It wasn't mentioned in the docs, but if you want to use TUN/TAP
networking, then you have to activate NAT on the host computer.
Steps I took (as root) to make it work:
1) Added a line in /etc/sudoers (using visudo) to allow me to
execute /etc/qemu-ifup as root:
kirk ALL=(ALL) NOPASSWD: /etc/qemu-ifup
2) Loaded the tun module:
modprobe tun
3) Gave myself access to /dev/net/tun:
chown kirk /dev/net/tun
4) Turned on forwarding:
echo 1 > /proc/sys/net/ipv4/ip_forward
5) As me, ran qemu. Note that I have perms for /dev/hdb8; it's a
partition I configured just for this experiment:
qemu -hda /dev/hdb8 -localtime -m 192
6) Turned on NAT:
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
You might be able to swap steps 5 and 6, but I'm not sure whether it's
necessary to have tun0 configged before starting NAT. I just got this
working late yesterday afternoon and haven't had time to refine it yet. :)
