Too bad that we did not manage to add a "Conflicts: vdsm <= 4.18.6" to
that release of python-ethtool-0.9-2.fc19.x86_64. But now that it is
out, there is not much that one can do but to upgrade to a new Vdsm or
roll back python-ethtool.

The propblem was due to Vdsm-proper using libnl1 while that version of
python-ethtool starting to use linbnl3 and solved by
http://gerrit.ovirt.org/26514. Backporting this to the now-unsupported
ovirt-3.3 is not really viable, I a m afraid.
