Thanks for the tips, I'll try it on the next system I bring up.  It's
usually only an issue when I install from scratch, so I haven't spent
much time working it out.  I get the bridge attached to eth0 before
installing any VMs and once it's set I don't usually have to touch it,
but Simon raises a good point that I'll keep in mind next time I do
have to mess with it.
