If you start a virtual machine with only one virtual network card, you will see tap<domID>.0 and vif<domID>.0 created and inserted into the xen bridge eth4. In your case, your Windows Vista is domain ID 13. So you should get tap13.0 and vif13.0. But in your case, vif13.0 cannot be created.

In your brctl show output, you have tap13.0 added to the eth4 bridge, but vif13.0 cannot be created and added to the same bridge. So I guess there's something wrong with your Xen networking.

For production environments, you might want to try CentOS or Scientific Linux.

You mean while it's attempting to start? See below.

I could probably get away with centos in a production environment, but
definitely not fedora. SLES10 is our current "standard". Unfortunately I
need usb functionality for a production server, whether that is or is
not recommended.

Thanks,
James
