In the VNIC case, the failure of the underlying physical NIC (resulting in the link being 'down') doesn't stop the different VNICs from communicating with each other. As a consequence we decided not to propagate the link state. If there is just one VNIC then perhaps it would make sense to do so. Even if we did fix this, the current Xen inter-domain protocol has no way to express 'link is down' (short of actually cutting the connection). _______________________________________________ networking-discuss mailing list [email protected]
