xennet
— Xen
frontend paravirtualized network interface
xennet* at xenbus?
The xennet
interface forms the frontend
part of the paravirtualized drivers 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
.xennet
and its associated endpoint use copy
mode for communication: packets are copied from one domain's memory to
another.The xennet
driver first appeared in
NetBSD 3.0.
The xennet
driver was written by
Manuel Bouyer
<bouyer@NetBSD.org>
and Christian Limpach
<chris@pin.lu>.
