A better venue for this kind of question would be the libvirt-users
mailing list, so please keep that in mind for next time :)

We backport security fixes to older releases, but not features.

So you would like to backport the feature yourself and build a Debian
package out of the result? Be warned, that would probably end up
being a massive amount of work, especially considering that you'd be
targeting a 2+ years old version of libvirt.

Can you really not simply install a newer package? libvirt has very
strong backwards compatibility guarantees, so ideally nothing should
break because of the update.
