Can you try the 12.04 qemu (which IIRC is 1.0) on > top of the newer kernel? I'm currently running the version included with Ubuntu 14.04: 2.0.0+dfsg-2ubuntu1.2. I had originally seen the hang with Ubuntu 12.04 (qemu 1.0+noroms-0ubuntu14.13) running the Canonical-backported-to-12.04 3.11 kernel. I'll try getting qemu 1.0 on two of my 14.04 / 3.13 machines this evening; migration results would come in tomorrow evening.
