There is the libvirt-tck testsuite (in perl) that can be used to validate various expected behaviors.  The kernel version is more likely to affect qemu-kvm behavior, and not libvirt proper, but running libvirt-tck can sometimes expose whether a qemu-kvm change (perhaps caused by a kernel change) was enough to cause user-visible regressions in libvirt behavior.  Beyond that, anything you can add to automate regression testing would probably be appreciated.
