I have something running along these lines, maybe it can help -
There are several things to check up when it comes to qemu networking

/usr/sbin/brctl addbr br0
/sbin/ifconfig eth0 0.0.0.0
/usr/sbin/brctl addif br0 eth0
/sbin/ifconfig br0 10.0.2.10 netmask 255.255.255.0 up
/sbin/route add -net 10.0.2.0 netmask 255.255.255.0 br0
/sbin/route add default gw 10.0.2.1 br0
/usr/sbin/tunctl -b -u $USER
/sbin/ifconfig tap0 up
/usr/sbin/brctl addif br0 tap0
/sbin/iptables -I RH-Firewall-1-INPUT -i br0 -j ACCEPT
/usr/bin/qemu -hda $DISK -no-acpi -m 2000 \
        -nographic -daemonize \
        -net nic,macaddr=52:54:00:11:22:33 \
                -net tap,ifname=tap0,script=no &
