Taking this excample, and assuming its for virbr0, then an radvd
config would simply comprise

  interface virbr0
  {
	AdvSendAdvert on;
	AdvManagedFlag off;
	AdvOtherConfigFlag off;

	prefix 2001:db8:1::/128
	{
		AdvOnLink on;
		AdvAutonomous on;
		AdvRouterAddr off;
	};
	prefix 2001:4978:2ac::/48
	{
		AdvOnLink on;
		AdvAutonomous on;
		AdvRouterAddr off;
	};
  };
