Qemu disk as installation target

To prepare a qemu disk as installation target run following commands and set disk=/dev/nbd0 in config.sh:

if ! lsmod | grep -q nbd; then sudo modprobe nbd max_part=8; fi # load nbd if missing
img="/var/lib/libvirt/images/ts-linux-testing.qcow2"
qemu-img create -f qcow2 -o size=20G $img  # create image
chown libvirt-qemu:libvirt-qemu $img       # make accessable for qemu
qemu-nbd -c /dev/nbd0 $img  # create device from image
qemu-nbd -d /dev/nbd0       # release device, after the installation is completed
