Comment # 10 on bug 903889 from Giacomo Comes

during the installation process the network configuration only uses a simple
network interface setup (no bridge). At the end of the installation process,
after all the rpm are installed and the final system configuration is created,
that is when you see on screen:

Save installation settings
* Saving network configuration...

in this moment in /mnt/etc/sysconfig/network are created the network files that
are used upon next reboot. There is ifcfg-br0, ifcfg-eth0 and the wrong
ifroute-eth0. 
I would say that it is the installer that when it decides to change the saved
network configuration (from non bridge to bridge because of the KVM pattern
getting installed) I does so correctly for the network interface but it forgets
to adjust the routing. In 13.1 this was done correctly. The bug was introduced
in 13.2.
