NAME
virt -- rump virtual network interface SYNOPSIS
#include <rump/rump.h> int rump_pub_virtif_create(int num); DESCRIPTION
The virt interface acts as a link between a rump virtual kernel and a host tap(4) interface. Interface number <n> always corresponds with the host tap interface tap<n>. All data sent by virt is written into /dev/tap<n> and all data read from /dev/tap<n> is passed as Ethernet input to the rump virtual kernel. A virt interface can be created in two ways: o Programmatically by calling rump_pub_virtif_create(). o Dynamically at runtime with ifconfig(8) or equivalent using the create command. Destroying a virt interface is possible only through ifconfig(8) destroy. The host's tap(4) interface can be further bridged with hardware interfaces to provide full Internet access to a rump kernel.
