I'm not very familiar with XenExpress, but I'm fairly sure that the management software used by XE is some proprietary code. Fedora uses

libvirt and virt-manager for management, has no artificial
limitations on memory, CPUs, guests etc., and is completely open source.

Does Fedora 8 have any way to limit the network speed on the guests?

I assume, though I've not tried it, that you should be able to use ordinary Linux mechanisms such as the 'tc(8)' command to enforce a traffic control and shaping on the vifX.0 devices.

To be honest, it's a bit of an unusual request: mostly people complain about not getting enough network performance :-)
