Instance Method Details

#bridgeable_candidates ⇒ Array<Y2Network::Interface]

Obtains the interfaces that are candidates for being bridgeable

Returns:

# File 'src/lib/y2network/virtualization_config.rb', line 41

def bridgeable_candidates
  builder = Y2Network::InterfaceConfigBuilder.for("br")
  builder.name = config.interfaces.free_name("br")

  config.interfaces.select { |i| connected_and_bridgeable?(builder, i) }
end

#create ⇒ Boolean

Iterates over the bridgeable candidates creating a bridge for each of them. The connection is copied to the bridge when exist and the interface is added as a bridge port

Returns:

  • (Boolean) —

    true when a new bridge was created
