Cluster level networking objects include:

  • Clusters
  • Logical Networks

A data center is a logical grouping of multiple clusters and each cluster is a logical group of multiple hosts. The following diagram depicts the contents of a single cluster.

Networking within a cluster

Hosts in a cluster all have access to the same storage domains. Hosts in a cluster also have logical networks applied to the cluster. For a virtual machine logical network to become operational for use with virtual machines, the network must be defined and implemented for each host in the cluster using the Red Hat Virtualization Manager. Other logical network types can be implemented on only the hosts that use them.

Multi-host network configuration automatically applies any updated network settings to all of the hosts within the data center to which the network is assigned.
