OpenVZ would be the only one I can name myself.

I've looked through some options of widely used "frameworks": Docker, rkt, LXC/LXD — all those are bridge-"centric" or at least based on broadcast media networking.

Instead I'm looking for convenient way of being able to assign any /32 IP-address to container and get proper bidirectional routing through "wormhole"/tunnel connecting guest and its host with minimal hacks or better w/o any.

    OK, so the crux of your Q is: "containers seem to do P2P via a bridged i/f on the host, are there any that do it more natively?"

    Veth pair can be used without a bridge. Assign IP addresses and you can communicate between container and host. When forwarding is enabled your containers can communicate outside/to other containers as well. Is your question about how to configure container networking without L2 bridging (I'm not familiar with OpenVZ networking)?
