How can we reproduce this? I just try the following command,

qemu-system-x86_64 -machine pc,accel=kvm -m 2048 -smp 2 -hda ubuntu.img

but at least I can boot that successfully and already live for a while. 
Here I installed ubuntu14.04 as a guest, and

Linux commit: aa39477b5692611b91ac9455ae588738852b3f60
Qemu commit: 7e58e2ac7778cca3234c33387e49577bb7732714

So any specific Kconfigs need to be enabled?
