Currently the live migration test job[1] is using relatively old version
of QEMU (2.0 -- 2 years old, 17-APR-2014).  And, libvirt 1.2.2
(released on 02-MAR-2014).  For libvirt, I realize there's an
in-progress thread[2] to get to a state to run a bleeding edge libvirt.

How can we go about bumping up QEMU to its newest stable release (2.5,

Matt Riedemann tells me on IRC that multi-node live migration job is
currently Ubuntu only, and to get a newer QEMU, it has to be added to
Ubuntu Cloud Archive.  It'd be useful to get that done.  Who can help
with it?  

It'll allow us to confirm our suspicion that a couple of Nova live
migration bugs[3][4] are likely fixed with that version.  Also it (the
newer QEMU) has some additional debug logging capabilities which can
help us with root cause analysis of some live migration issues.
