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
/usr/sbin/brctl addif br0 eth0
/sbin/ifconfig br0 netmask up /sbin/route add
-net netmask br0 /sbin/route add default gw 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 &
