OpenBSD has some network virtualization (not yet fully ready?) stuff in the tree called rdomain. I reading the current documentation, but i dont find any solution to interconnect two rdomain. I create two vether interface in different rdomain and switched them, but it doesnt work. So that would be nice if this vwire (or similar) device will be provided and coexist with rdomain.
Ps: FreeBSD has an epair(4) device for its vimage virtualization solution, something similar for rdomain would be great.
