Comment 8 for bug 1374568

verified.

Our system is connected through eth0 to a network that has a functional
maas running. As such, we can boot guests that dhcp onto the network and
should network boot.

Configuring maas is beyond the scope of this verification report.

# enable proposed
$ mirror=http://ports.ubuntu.com/ubuntu-ports
$ echo "deb $mirror trusty-proposed main universe" |
   sudo tee -a /etc/apt/sources.list
$ sudo apt-get -q update

## to get a functional qemu-system-ppc64, we use kilo cloud archive
$ sudo apt-add-repository -y cloud-archive:kilo-proposed
$ sudo apt-get update
$ sudo apt-get install -qy qemu-system-ppc qemu-slof

$ dpkg-query --show qemu-slof
qemu-slof 20140630+dfsg-1ubuntu1~14.04

# configure eth0 to be a bridge
$ sudo apt-get install -qy bridge-utils
$ ifdown eth0
$ eni="/etc/network/interfaces"
$ cp "$eni" "$eni.dist"
$ cat > "$eni" <<EOF
auto lo
auto br0
iface br0 inet dhcp
   bridge_ports eth0
EOF

ifup br0

## setup kvm, we're running linux-generic-lts-utopic kernel
$ uname -r
3.16.0-30-generic

$ sudo sh -cx 'grep "kvm_" /proc/modules || modprobe kvm_hv || modprobe kvm_pr'
$ sudo chmod 666 /dev/kvm
$ sudo ppc64_cpu --smt=off

## try booting a qemu-system-ppc via netboot
$ myname=$(id -un)
$ sudo ip tuntap add mode tap user $myname mytap0
$ sudo ip link set mytap0 up
$ qemu-system-ppc64 -machine pseries,usb=off \
    -device spapr-vscsi \
    -device spapr-vlan,netdev=net00 \
    -netdev type=tap,id=net00,script=no,downscript=no,ifname=mytap0 \
    -boot n -display none -nographic -m 4G -echr 0x05

## eventually this will show 'booting under maas direction'
## and the system is even enlisted into maas
