Creation of Logical Networks on RHEV


Logical Networks allow segregation of different types of traffic. According to Red Hat Training Manual, it is recommended to have 3 types of network

  1. Management Network – Network to connect hypervisor (RHEV-H) nodes to the RHEV Manager
  2. Storage Network – Network to connect RHEV-H  to NFS and iSCSI. If you are using FC, there is no need to create a separate network since it is using SAN
  3. Public Network –  Connect the Gateway Router, the RHEV-M systems and RHEV-H Nodes
