+UBUNTU: Suppress ioemu agrument even when model name given
+
+A strange bug in the xm stack will cause the paravirt interface
+to have no MAC address when type=ioemu is used in the vif definition.
+However for the default emulation and any other hw emulated NIC,
+there will always be a paravirtualized NIC present. And the guest
+will unplug the emulated interfaces when the platform device
+is present. In short type=ioemu only can hurt, it never adds
+anything that would not be done anyways.
