I would suggest you fire up wireshark in Dom0 and monitor for DHCP
traffic while you start the guests.
My best guess is that your academic network might be applying
per-port limits on IP addresses and you are only allowed 3 at one
time - and are using them all (1 for Dom0, two for DomUs). It might
be worth asking the admins if they apply any such limits.
