Using the Virtual Network Configuration module, you can create network bridges and attach them to virtual machines. You can also assign physical interfaces on the host to bridges.
To create a bridge, enter a name and click "Create" in the "Create Bridge" section. All other parameters are optional. If not specified, the bridge will be created with default values. Except Name, STP and Priority, you can change all the other parameters in the Bridge Configuration module after the bridge is created.
Use the "Add Bridge to VM" section to attach a bridge to a virtual machine.
To assign interfaces on the host to a bridge, specify the bridge name and the host interface in the "Add Interface to Bridge" section. Click "Add". You can add multiple interfaces to the same bridge using the aforementioned method. The Cost and Priority parameters are optional.
