1.2.10 PXE Boot Fails Due to Incorrect Host Name Configuration

If the Spacewalk server was installed without a fully-qualified domain name (FQDN) specified, or with a name that cannot be resolved in DNS, Spacewalk creates invalid Preboot eXecution Environment (PXE) boot configuration files.

You can validate that Cobbler is configured correctly by checking that the IP address that is used in the ks= parameter in the /var/lib/tftpboot/pxelinux.cfg/default file is correct.

To reconfigure a Spacewalk server after an installation, do the following:

  1. Edit the /etc/cobbler/settings file and change all instances of incorrect host names, such as localhost.localdomain.

  2. Restart Spacewalk by running the spacewalk-service restart command.

  3. Resynchronise Cobbler by running the cobbler sync command.
