Resolution

Navigate to cobbler's configuration settings at /etc/cobbler/setttings.yaml and change the "redhat_management_server: abc" to actual SUSE Manager FQDN i.e. "redhat_management_server: abc.xyz.com".

And restart the spacewalk services:

spacewalk-service restart

Cause

After migration to SUSE Manager 4.3, the settings.yaml file can be overwritten with new shortname of the SUSE Manager system. Causing this issue to occur.
