What is in your /etc/qemu-ifup?

I just have the following in /etc/network/interfaces:

  iface eth1 inet dhcp
  auto eth1

I have enabled everything in:

=== /etc/qemu-ifup ===

sudo -p "Password for $0:" /sbin/ifconfig $1
echo "Executing /etc/qemu-ifup"
echo "Bringing up $1 for bridged mode..."
sudo /sbin/ifconfig $1 promisc up
echo "Adding $1 to br0..."
sudo /usr/sbin/brctl addif br0 $1
sleep 2

=== END ===

It needs to bridging. After running qemu with cd-image.iso, I get:

=== OUTPUT ===

Bringing up tap0 for bridged mode...
Adding tap0 to br0...
bridge br0 does not exist!

=== END ===

hence "arping -i tap0 04:EA:43:01:96:09 -w 100 -c 10000" gives:

arping: libnet_get_ipaddr4(libnet): libnet_get_ipaddr4(): ioctl():
Cannot assign requested address
