Comment 2 for bug 1734167

I'm not using the included kernel or initrd, so I decided to test without that.

kvm -machine pc-i440fx-zesty,accel=kvm,usb=off,dump-guest-core=off -m 4096 -smp 3 -cpu Opteron_G3 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:31:33:70,bus=pci.0,addr=0x3 -netdev bridge,id=hostnet0 -drive file=testful.img,if=virtio -smbios "type=1,serial=ds=nocloud-net;s=https://raw.githubusercontent.com/mlyle/mlyle/master/cloud-metadata/linuxtst/"

Properly gets the hostname of 'linuxtst' and all associated configuration on xenial, but not on artful.
