2) Many VEs in many communities spread across many hosts.  For
example, it might get bad if you had 5 communities across 100 hosts,
with each community having 100 VEs.  This would mean each host needs
a full set of 10000 MAC rules for each community - 50000 ebtables
rules.  In this case, I'd again prefer a routed design (well, any case
actually...) and if a common "community" LAN was a software
requirement, I'd use multipoint GRE or L2TP.

But for one node with a bunch of unrelated VEs, this is very little
work to maintain.

In my particular configuration, there are no communities - each VE is an island, and will only be able to communicate with the network gateway (which is non-local, ie. not on the linux bridge itself.) That should lock down layer 2. With OpenVZ, each VE's MAC will have a common SWSoft 00:18:51 prefix.

After I get that working, I need to lock down layer 3 with iptables, so the PVLAN functionality can't be bypassed.

If you have any configuration examples for ebtables, especially simple ones, I would welcome them :)

Thanks,

Daniel
