As far as I can see, you did not specify the CPU type in your parameter
list, so try to add a "-cpu POWER8" to see if that helps.
Then, in case you still have trouble, try to omit the virtio-balloon
device ... there have been some endianess issues with that device in the
past, and if Ubuntu did not pick up these patches yet, it might cause
some trouble.
