The problem actually was with another misconfigured xen machine. Basically the result of a botched attempt to install xen3 on that machine. Basically that was the machine sending out FF:FF:FF:FF:FF:FF packets which confused the heck out of this xen machine. So now that the old, misconfigured xen machine is off and all its guests moved to this new FC5 machine, all is well. The network settings all worked right out of the box with no need to mess with anything. thanks for the help.
