OK, What obvious bit of networking wisdom am I missing? Everything I try
that diverges in the slightest from the default bridge configuration
results in a network that is utterly non-functional.

The simplest case I've tried created a bridge at boot time using the
debian /etc/network/interfaces file to define it, and replaced the
network-bridge script with a much simpler one that basically does
nothing.

My theory was this would give me a network where the virtual machines
could speak to one another (since they are connected to the bridge), but
not the outside world.

But what I get is VIFs being connected to the bridge by the vif-bridge
script, and eth0 being created in the virtual machines, but I can't
ping any virtual machine from any other one - ping just times out
waiting for something to happen.

I've tried many more complex schemes as well, with the same result :-).
