You need to test with the following setup:
* The source needs to run qemu 1.5. (which should be unpatched)
* The destination needs to run a *PATCHED* versions of qemu 2.0 and libvirt 1.2. Furthermore, libvirt *NEEDS* to have allow_incoming_qemukvm set to true.

Failure to set allow_incoming_qemukvm to true will result in this error:

Length mismatch: 0000:00:03.0/virtio-net-pci.rom: 20000 in != 40000
qemu: warning: error while loading state for instance 0x0 of device 'ram'

Your logs show that you failed to follow the test steps as the destination isn't using the "pc-i440fx-1.5-saucy" machine type as expected.

Make sure libvirt is properly configured and restarted with "allow_incoming_qemukvm".

The proposed patches (both libvirt and qemu) have been running in production environment without any issue since the bug report.
