Creating logical networks
As explained earlier, logical networks are nothing but the bridges configured on the oVirt nodes. They are created in order to segregate the traffic. For example, if you use the ovirtmgmt logical network for every purpose, including the VM traffic, which includes live migration traffic, display traffic, and so on, it can choke the bandwidth. Therefore, we create multiple logical networks using different NICs based on the VM traffic and purpose. To create a logical network, follow these steps:
- Go to the Network tab and click on New Logical Network.
- Select your Data Center and enter a name for the logical network. Here, it is
vmdata. - Make sure that the VM network option is enabled and click on OK, otherwise it will create a non-bridge interface, which can only be used for VM live migration or to display network traffic.

Once the logical network is created, you have to apply that logical network to each host. If this step is not done, your host status will change...
