xennet -- Xen frontend paravirtualized network interface
xennet* at xenbus?
The xennet interface forms the frontend part of the paravirtualized driv- ers used by Xen guest domains to have network connectivity. When the host domain is NetBSD, the endpoint of the xennet interface is a xvif(4) interface. In the XenStore, xvif and xennet are identified by ``vif'' (virtual interface) entries. Conceptually, frontends and backends drivers are similar to two Ethernet cards connected via a crossover cable. xennet interfaces can pass VLAN tagged packets.
xennet%d: can't read mac address, err %d The MAC address for this inter- face could not be read from XenStore. xennet%d: %s is not a valid mac address The MAC address specified in the configuration file of the newly created guest domain is invalid. xennet%d: using event channel %d The Xen event channel (virtual inter- rupt) ID associated to this xennet. xennet%d: using RX copy mode The xennet and its associated endpoint use copy mode for communication: packets are copied from one domain's memory to another. xennet%d: using RX flip mode The xennet and its associated endpoint use flip mode for communication: packets are passed by remapping memory pages between domains.
