        <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>
