I'm guessing it has to do with spanning tree (portfast) setting on
your switch. Try changing you current setting.

When functioning as Xen dom0, the server will behave (networking-wise)
more like a switch instead of a single host, so some adjustments might
be required on your uplink switches. Set it the same way you would if
its connected to another switch.
