示例1: electBridgeIPv4

func electBridgeIPv4(config *NetworkConfiguration) (*net.IPNet, error) {
	// Use the requested IPv4 CIDR when available.
	if config.AddressIPv4 != nil {
		return config.AddressIPv4, nil
	}

	// We don't check for an error here, because we don't really care if we
	// can't read /etc/resolv.conf. So instead we skip the append if resolvConf
	// is nil. It either doesn't exist, or we can't read it for some reason.
	nameservers := []string{}
	if resolvConf, _ := readResolvConf(); resolvConf != nil {
		nameservers = append(nameservers, getNameserversAsCIDR(resolvConf)...)
	}

	// Try to automatically elect appropriate bridge IPv4 settings.
	for _, n := range bridgeNetworks {
		if err := netutils.CheckNameserverOverlaps(nameservers, n); err == nil {
			if err := netutils.CheckRouteOverlaps(n); err == nil {
				return n, nil
