We build the GlusterFS packages against the current version of CentOS 7.
The dependencies that are installed during the package building may not
be correct for older CentOS versions. There is no guarantee that the
compiled binaries work correctly on previous versions. The backwards
compatibility only counts for new OS updates, so that old applications
do not need to be recompiled. This request is the other way around, and
is not something I think we can commit to keep working.

The correct solution would be to update all the dependencies (and their
dependencies like a chain) to not run into unexpected and difficult to
debug problems. Downgrading libvirt or keeping it on an older version
should be possible.
