mode=bridge | vepa

Optional and mutually exclusive with network; indicates whether packets are delivered to the target device or to the external bridge.

bridge: If packets have a destination on the host from which they originated, they are delivered directly to the target. For direct delivery, both origin and destination devices need to be in bridge mode. If either the origin or destination is in vepa mode, a VEPA-capable bridge is required.
vepa: All packets are sent to the external bridge. If packets have a destination on the host from which they originated, the VEPA-capable bridge will return the packets to the host.

network

Optional and mutually exclusive with mode; specifies the name of a virtual network.
