The problem is that we need to link probes.o to libvirtmod. Now, After we do it, it shows another problem in libvirtmod as the link showed. https://www.redhat.com/archives/libvir-list/2012-February/msg00249.html these two issue could be solved together.
According to the mail thread in comment 3. The problem is made by the python library link against 'libvirt_util.la'.
The patch has been ACKed and pushed, and I verified the patch, it indeed works well for me, so move the bug to POST status, please change bug status if it has still any question. commit f2445e4de70547e32a6bcec3e1e8e51f02ac5b36 Author: Michal Privoznik <mprivozn> Date: Tue Feb 7 13:30:42 2012 +0100 pyhton: Don't link against libvirt_util.la As we already link with libvirt.la which contains libvirt_utils.la. Double linking causes global symbols to be presented twice and thus confusion. This partially reverts c700613b8d463212d142c97108b7a2352e23e559
