Your supervdsmd has

    MainProcess|Thread-26::DEBUG::2014-01-27 15:51:48,866::configNetwork::561::Storage.Misc.excCmd::(setSafeNetworkConfig) '/usr/share/vdsm/vdsm-store-net-config' (cwd None)

which reports success, too.

Maybe you can debug the issue:
Setup up a network but do not save it yet.
Log into your ovirt-node.

You should see /etc/sysconfig/network-scripts/ifcfg-<YOURNET>
and /var/lib/vdsm/netconfback/ifcfg-<YOURNET>, the
latter meaning that it's not yet persisted.

Now run locally
  vdsClient -s 0 setSafeNetworkConfig

You should see /config/etc/sysconfig/network-scripts/ifcfg-<YOURNET>
created, and /var/lib/vdsm/netconfback/ifcfg-<YOURNET> gone.

Now please run
    /usr/share/vdsm/vdsm-restore-net-config
which should do absolutely nothing.

If the process above breaks, it's a Vdsm bug. If not, it most probably
something in ovirt-node.
