After standard installation, reboot the VM and close qemu (it won't reboot properly anyway). Then start Breezy from the harddisk:
sudo qemu -hda breezy.img -m 512
Log in and check if you can reach your workstation (the host) and if you can reach the Internet.
On teh virtual machine, change the repositories (you must be root):
cat << HERE > /etc/apt/sources.list
