Hello,

Sorry in advance if I am asking questions at the wrong place.

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

I would like know if we have plans to backport new features to old releases, for example block copy remote disks.

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

If the answer is no, then where can I find some guidance on building a libvirt debian packages?

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. -- Andrea Bolognani / Red Hat / Virtualization
