LAB: Set up a lab.

If you are serious about passing RHCSA & RHCE exams, you have to build a lab.
There are very limited explanations in books and almost no article on Internet on this topic (one such article about building a lab for RHCSA/RHCE exams) and it’s not so easy.

This task can be split into several steps:

• Check hardware requirements,
• Satisfy software requirements,

(if you go the Virtual Box way, my explanations stop here)

• Install a KVM host,
• Configure network settings,
• Set up a repository,
• Configure a DNS service,
• Create a VM guest.

Additional information is available about the virsh command and the KVM configuration in CentOS 6.4.
Furthermore, Dell provides basic installation instructions and more advanced instructions.
Finally, the CentOS wiki offers a tutorial on KVM virtualization.
