btw, shouldn't we, in the general case, create a bridge per user and use
IP NAT? If we have a global bridge, users can spoof each other's MAC
addresses and interfere with their virtual machines. They can also
interfere with the real network.
That's not a concern with most one-user-per-machine configurations, but
the default configuration should be safe.
