After configuring the network during installation, the network is not set up correctly after the initial reboot. The configuration file /etc/sysconfig/network-scripts/ifcfg-pci3p1 contains the following lines: ... ONBOOT="yes" NM_CONTROLLED="yes" ... As the NetworkManager is not installed by the "Minimal" pattern, this prevents the device from being initialised with the correct network configuration. A workaround seems to be setting NM_CONTROLLED="no" or chkconfig network on and restarting the network afterwards
