Comment 46 for bug 632696

I also had this behaviour on 12.10 (upgraded from 12.04)

virt-install was repeatedly not working
sudo virt-install --name=lin01 --ram 1024 --disk path=/var/lib/libvirt/images/disk1.img,format=raw,bus=virtio,cache=none,size=2 --disk path=/var/lib/libvirt/images/disk2.img,format=raw,bus=virtio,cache=none,size=1 --network network=default,model=virtio --nographics --accelerate --os-type=linux --os-variant=debiansqueeze -x 'DEBIAN_FRONTEND=text console=ttyS0,115200n8' --location=http://ftp.debian.org/debian/dists/squeeze/main/installer-amd64/

same errors as above

I took @jdstrand's suggestion from https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/632696/comments/19
and came up with the following (I am new to apparmor so I do not know all implications of this change)
