Does anyone know if there are issues using
swarm/overlay
networking between Xen VPS hosts?
I can't see any reason why there would be a problem, but I don't
know anything about vxlan.
Are you saying that when you tcpdump on one host looking for port
4789 traffic (TCP? UDP?), you do not see anything when you think you
should?
You should be able to send any unicast traffic you like, though you
cannot do broadcast / multicast since each VM is in its own
broadcast domain with just itself and the host its on.
Cheers,
