Thank you for your work. I'm sure a lot of people will benefit from it.
Live migration is a major keystone to our operation excellence and
anything that can improve it is welcomed.

I see the package is built against Wily. Will it work against Trusty? I
would say yes. It depends on libvirt0 (>= 1.2.16-2ubuntu11) which is
already available in the liberty repo of UCA.

Meanwhile, I managed to package 1.2.20 for test purposes for both Trusty
and Precise (not without raging =) as I needed to move on.

On a side note, I feel libvirt is such an important piece that it would
warrant its own official PPA. (both libvirt and libvirt-python)

I added comments to the review [1] because the change doesn't work in
its current state. I tested the patch against Kilo + Trusty + libvirt

My main challenge at the moment is backporting the patch further to
Icehouse+Precise so I can move instances out of precise nodes and
upgrade them to trusty. Some far, and this is very early results, my
instances are stuck in "MIGRATING" state although they were completely
migrated to the destination. (domain is running on destination, removed
from source, ping is responding and I can SSH fine)
