In this chapter, you learned:
A data center consists of a collection of logical resources, including clusters, hosts, logical networks, and storage domains.
A cluster is a group of hosts in a single data center that act as a migration domain for virtual machines. The hosts do not need to have the same CPU physically, but their hardware does have to match the features that the cluster's CPU type provides.
The CPU type of the cluster specifies which CPU features are supported by the hardware of every host in the cluster.
The installation process automatically creates a data center named Default containing an empty cluster named Default.
Additional data centers and clusters can be created in the RHVM Administration Portal.
Click CREATE to build all of the virtual machines needed for the classroom lab environment. This may take several minutes to complete. Once created the environment can then be stopped and restarted to pause your experience.
If you DELETE your lab, you will remove all of the virtual machines in your classroom and lose all of your progress.
