Simplicity? netmap would probably be the most performant solution, A host bridge device with taps per guest with a vtnet device in the guest would probably be the simplist. By not attaching the bridge to a host adapter and not giving it an IP on the host the host is left out of the communications, BUT it can debug most any of it with tcpdump. -- Rod Grimes rgrimes@freebsd.org
