Thanks, I would appreciate clarification on this point.

This bug is very similar, except I can reproduce the problem on precise too:
https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1403841

>From Eric Blake's commentsin the libvirt-users thread above, it sounds like there
were a number of improvements in several newer libvirt releases to address
problems where the active config was not being flushed to disk. It looks like the
particular code path in 1403841 has been fixed, however others seem to exist. I'm
not sure how feasible it would be to cherry-pick all fixes for this problem from
newer libvirt releases verses supporting a backport of newer stable libvirt.

Thanks,

Andrew
