A logical network is mainly used to isolate network traffic by functionalities. You can run your virtual workloads on a host with a single Network Interface Controller (NIC), but it is not recommended to run your mission critical workloads for optimal performance. The following are five different types of network traffic you need to consider during the design phase of RHEV:
RHEV-M network: This is the first logical network created by the RHEV hypervisor installer and attached to the specific NIC of your hypervisor host. It is primarily used for manager and hypervisor heartbeat communication, and also for live migration of virtual machines.
Virtual machine networking traffic: This type of network traffic is primarily used by your application and end user to access the application that runs on the guest.
Storage network: This network is primarily used in a scenario where network storage such as NFS or iSCSI is used as data domains to segregate storage traffic.
Live migration traffic...
