Virtual Network
Oracle VM Server for SPARC uses the virtual network device and virtual network switch device to implement virtual networking. The virtual network (vnet
) device emulates an Ethernet device and communicates with other vnet
devices in the system by using a point-to-point channel. The virtual switch (vsw
) device primarily functions as a multiplexor of all the virtual network's incoming and outgoing packets. The vsw
device interfaces directly with a physical network adapter on a service domain, and sends and receives packets on behalf of a virtual network. The vsw
device also functions as a simple layer-2 switch and switches packets between the vnet
devices connected to it within the system.
