2.2.3. Networking

This section describes what behaviors have changed in the graphical installer, relating to networking.
  • Anaconda is now using NetworkManager for configuration of network interfaces during installation. The main network interface configuration screen in Anaconda has been removed. Users are only prompted for network configuration details if they are necessary during installation. The settings used during installation are then written to the system for later use.
  • When PXE booting and using an .iso file mounted using NFS for the installation media, add repo=nfs:server:/path/ to the command line. The install.img and product.img files also need to be extracted and placed into the nfs:server:/path/images/ directory. The product.img file contains variant definitions and various install classes.
  • Some systems with multiple network interfaces do not assign eth0 to the first network interface as recognized by the system BIOS. This can cause the installer to attempt to use a different network interface than was initially used by PXE. To change this behavior, use the following in pxelinux.cfg/* configuration files:
    IPAPPEND 2
    APPEND ksdevice=bootif
    This configuration option causes the installer to use the same network interface as the system BIOS and PXE use. You can also use the following option, which will cause the installer to use the first network device it finds that is linked to a network switch:
    ksdevice=link
