[Bug 1432630] [NEW] libvirt tunnelled migration fails with "migration job: unexpectedly failed"

[Lukas Vacek]

Public bug reported:

There is a bug in libvirt in up-to-date Ubuntu 14.04.2 LTS when live
migrating a VM with a big storage attached to it - the migration fails
with "error: operation failed: migration job: unexpectedly failed". Not
sure what's the threshold for the storage size to trigger  the bug, but
I can migrate a guest with 8GB storage between nodes but a guest with
30GB storage fails to migrate. This only happens when --tunnelled
parameter is passed to "virsh migrate".

# virsh migrate --live --p2p --copy-storage-inc --tunnelled ubuntuutopic-small "qemu+tcp://lab5/system"
error: operation failed: migration job: unexpectedly failed

#on the other hand, this WORKS OK:
virsh migrate --live --p2p --copy-storage-inc  ubuntuutopic "qemu+tcp://lab6/system"


libvirt: 1.2.2-0ubuntu13.1.9
qemu: 2.0.0+dfsg-2ubuntu1.10
linux kernel: 3.13.0-46-generic #79-Ubuntu

Versions are same on both boxes.

libvirtd.conf only changed to listen on TCP and not to require
authenitcation.

Logs and the domain xml attached.
