<div>I was going to wait until I did some more testing, but
since I'm on this topic:</div>
<div><br>
</div>
<div>I have done some preliminary tests with the latest libvirt
packages from Ubuntu (available in both 12.04 and 14.04). The
tests were done in a 12.04 Icehouse environment that supports
live migration. I created several instances using the stock
qemu and libvirt packages and then upgraded both sets of
packages.</div>
<div><br>
</div>
<div>Hard rebooting, live migration, and hard reboot of
live-migrated instances were all successful.</div>
<div><br>
</div>
<div>I still want to run through the tests a few more times
(especially migrating to 14.04 hosts), but it looks as though
the latest Ubuntu packages resolve any backwards compatibility
issues.</div>

</span>There is some work on Ubuntu's side to get a clean
migration path, see:<br>
