We could run a separate instance of radvd using a custom configuration
file (-C option), limiting it to the bridge interface, like so:

interface virbr0
{
	IgnoreIfMissing on;
	AdvSendAdvert on;
	MinRtrAdvInterval 30;
	MaxRtrAdvInterval 100;
	AdvDefaultPreference low;
	AdvHomeAgentFlag off;

	#bernie: we actually have a /48, thus 65536 /64 subnets
	prefix 2001:4978:243:1::0/64
	{
		AdvOnLink on;
		AdvAutonomous on;
	};
};
