VIRT(4)                    Kernel Interfaces Manual                    VIRT(4)

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.
