Do you have any desired parameters?
Performance Driven?  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.
