# NAME

`virt` — rump kernel virtual network interface

# DESCRIPTION

The `virt` interface acts as a link between a rump 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 kernel.

A `virt` interface can be created and destroyed in the normal fashion with ifconfig(8).

The host's tap(4) interface can be further bridged with hardware interfaces to provide full Internet access to a rump kernel.
