Probably there will be some other things to sort out, control plane? (depending on deployment type). I'm not aware of any live deployments running FreeBSD and VXLAN. We do have live deployments on Linux using VXLAN ecnap (Linux + tungsten fabric or similar). I will love to know about any live deployment/successful stories on FreeBSD + VXLAN + bhyve and Jails. Unfortunately my BSD daily usage is more related to  Jails + VNET + FRR and netmap. These amazing tools allow us to quickly "simulate" 10s of CPE devices, generate routes,  OSPF/BGP/BFD speakers, and generate traffic while staying away from all the Linux craziness (and other tools are super expensive). It will be nice to do a test and see how good FreeBSD integrates into an existing overlay. I hope it make sense.
