VIRT(4) FreeBSD 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.
