We have already installed Spacewalk server from which we can control all of our systems. In order to do that, we now need to install our client systems and register them to our Spacewalk server.
Spacewalk is an open source Linux systems management software. Spacewalk is the upstream community project, derived from Red Hat Satellite software.
Using Spacewalk, we can easily configure, manage and deploy software packaged to Linux distros such as CentOS, Red Hat, Fedora and such. It has nice web interface, that we can use to monitor the status of software updates on our servers and start update process. Spacewalk provides provisioning capabilities that enables the user to kickstart provision systems and manage and deploy configuration files. This piece of software also has virtualization capabilities to enable you to provision, control, manage, and monitor virtual KVM and Xen guests.
