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.
/var/lib/vdsm/netconfback/ifcfg-<YOURNET> is not removed on oVirt Node
as /var/lib/vdsm/netconfback is sitting on a tmpfs so there was no
need to call it for the reboot case.
We made some more tests with Francisco on #ovirt today and we saw that
for some unknown reason, when rebooting the machine the ifcfg-<YOURNET>
files disappear while the rule-<YOURNET> and route-<YOURNET> stay. That
happens even when the both ifcfg, rule and route have the correct entry
in /config/files and are bound to /config/etc/sysconfig/
After reboot it returns to eth0 having the connectivity as it was defined
with the TUI.
For libvirt networks a bit of the same as for ifcfg files. Before reboot
/etc/libvirt/qemu/networks is present in /config/files and findmnt reports
that /etc/libvirt/qemu/networks is a bound mount of /config/etc/libvirt/qemu/networks.
After reboot it is not the case anymore.
@Fabian: Do you think there is something on the reboot that restores the
network conf to the TUI settings?
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.
