The tap devices correspond to emulated interfaces, vif devices are used by paravirtualized drivers in the guest. Xen will switch over to the vif devices if and when the paravirtualized drivers come up. This really is a Xen question, not an Open vSwitch one. Please ask such questions on the Xen mailing lists in the future. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
