A bridge doesn't require an IP address.
True, but that's the simplest way to setup networking so all the virtual machine will be in the same subnet with my PC and look like "real" machines to the rest of the network.
At my work, this was done because there were more devices than available addresses. If you rebooted, you risked not being able to get an IP. We negotiated for a small block of fixed addresses for the servers in my group.
Not a problem at work, they were just completely reorganizing the network in prep for moving to a new building. We are moved now and things are stable again. I probably could just go back to static IP (which always seemed to work).
If you can do a script you could just try getting dhcp to assign an address in a loop until it works.
I have managed to bring the network up after booting, but then lots of network services have failed to start and I have to track them all down as well, rebooting till it works is easier :-).
